ARM: dts: am437x: pixcir_tangoc: use correct flags for irq types
Now IRQs for Pixcir Tangoc touchscreen are defined using IRQ_TYPE_NONE in am437x-gp-evm.dts and am43x-epos-evm.dts wich do not correspond HW. Hence, update am437x-gp-evm.dts and am43x-epos-evm.dts files and use correct flag IRQ_TYPE_EDGE_FALLING for irq types. While here, remove duplicated irq declaration for pixcir_ts@5c node in am437x-gp-evm.dts. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> |

ARM: dts: am4372: fix irq type for arm twd and global timer
As per ARM documentation PPI(0) ID27 - global timer interrupt is rising-edge sensitive. PPI(2) ID29 - twd interrupt is rising-edge sensitive. and the same is proved by GIC distributor register value GIC_DIST_CONFIG(0xC04) = 0x7DC00000. Hence, set IRQ triggering type to IRQ_TYPE_EDGE_RISING for ARM TWD and Global timers. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> |

tree wide: use kvfree() than conditional kfree()/vfree()
There are many locations that do
if (memory_was_allocated_by_vmalloc)
vfree(ptr);
else
kfree(ptr);
but kvfree() can handle both kmalloc()ed memory and vmalloc()ed memory
using is_vmalloc_addr(). Unless callers have special reasons, we can
replace this branch with kvfree(). Please check and reply if you found
problems.

ARM: omap2plus_defconfig: Enable ARM_KERNMEM_PERMS and few loadable modules
With recent omap assembly fixes for CONFIG_DEBUG_RODATA, we can now use DEBUG_RODATA. Let's enable ARM_KERNMEM_PERMS so that DEBUG_RODATA gets selected by default. This way we can make sure any related issues are caught early. And while testing things on various devices, I noticed we're missing few loadable modules to make things more usable: - USB Ethernet for smsc75xx, we only have smsc97xx right now - Basic USB serial drivers for things like ftdi and pl2303 ports - Blinking leds with pca963x Signed-off-by: Tony Lindgren <tony@atomide.com> |

ARM: realview: fix device tree build
As it happens, two obj-$(CONFIG_FOO) += foo.o variables are above obj-y := core.o, which doesn't work: the += directives need to add something to the build and doesn't work if obj-y is not set first, so move the obj-y to be on top and everything builds nicely again.

More power management and ACPI updates for v4.5-rc1
- Modify the driver core and the USB subsystem to allow USB devices
to stay suspended over system suspend/resume cycles if they have
been runtime-suspended already beforehand and fix some bugs on
top of these changes (Tomeu Vizoso, Rafael Wysocki).
- Update ACPICA to upstream revision 20160108, including updates
of the ACPICA's copyright notices, a code fixup resulting from
a regression fix that was necessary in the upstream code only
(the regression fixed by it has never been present in Linux)
and a compiler warning fix (Bob Moore, Lv Zheng).
- Fix a recent regression in the cpuidle menu governor that broke
it on practically all architectures other than x86 and make a
couple of optimizations on top of that fix (Rafael Wysocki).
- Clean up the selection of cpuidle governors depending on whether
or not the kernel is configured for tickless systems (Jean Delvare).
- Revert a recent commit that introduced a regression in the ACPI
backlight driver, address the problem it attempted to fix in a
different way and revert one more cosmetic change depending on
the problematic commit (Hans de Goede).
- Add two more ACPI backlight quirks (Hans de Goede).
- Fix a few minor problems in the core devfreq code, clean it up
a bit and update the MAINTAINERS information related to it
(Chanwoo Choi, MyungJoo Ham).
- Improve an error message in the ACPI fan driver (Andy Lutomirski).
- Fix a recent build regression in the cpupower tool (Shreyas Prabhu).

Pull more power management and ACPI updates from Rafael Wysocki:
"This includes fixes on top of the previous batch of PM+ACPI updates
and some new material as well.
From the new material perspective the most significant are the driver
core changes that should allow USB devices to stay suspended over
system suspend/resume cycles if they have been runtime-suspended
already beforehand. Apart from that, ACPICA is updated to upstream
revision 20160108 (cosmetic mostly, but including one fixup on top of
the previous ACPICA update) and there are some devfreq updates the
didn't make it before (due to timing).
A few recent regressions are fixed, most importantly in the cpuidle
menu governor and in the ACPI backlight driver and some x86 platform
drivers depending on it.
Some more bugs are fixed and cleanups are made on top of that.
Specifics:
- Modify the driver core and the USB subsystem to allow USB devices
to stay suspended over system suspend/resume cycles if they have
been runtime-suspended already beforehand and fix some bugs on top

ARM: SoC defconfig updates for v4.5
As usual, a bunch of commits, mostly adding drivers and other options to defconfigs because it makes sense to have them enabled on various development or product boards. Too much to enumerate each here. There's an introduction of a pxa_defconfig, since PXA finally will allow building a shared kernel for all boards. With this, we can hopefully remove a bunch of individual defconfigs down the road but it requires a bit of real life testing and transition period. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWnsEkAAoJEIwa5zzehBx33lcQAItHXIplC5tC3EjnJLY2lW8j bZ38mWVU0I5jT688hlCw7eOCajO30sG0RM4vqlG1PpvL6mbiM3kX6s0LBUVQa6J0 bCHLkzVkXBXO3VJFAHcY821XdBpnINgmAt/AEElSDrBK2wi/kb6dvP0ClYe/4zhB B44P/pWtYpn09KyGkPdIanSGPG0ikvP03i0mKRxlFwyB2RSJiFzsVlNtUYQMgDMp SOsN3fO2AzZCWCNF+gz7/ekWzo7hGlXNU3WeIIWIs3GL6FTi9p//LeP7w9oTxGbv d6hId6TGp7rYCA0XjwJtRK1kkQGVLxCltR/UDBSCjc4sS4Xh8ME35TDWo1Z/yHKr UtlKI2VHMSkxkk1DChbUYS8ojBOmgVApvG4BTYm0DICvW7zeGJqtOD/zM5CgKJWA AfVAL2c9N47YyOYcehDucig+yuxf4+RV92hEO+K84MWL1MYi5o/J3BJqmQ7dtfBT MYLLgcpzsUPC9R43mUs69/zojBFCPPPIz6CBn29m9+BAkX887jvInln7fKK0TaG8 V9Y0eHmgEHvshomYrJwkFKSIq7NhU0M+ZCGvBNP5a1wDNEw/Kc0/Sz1QVHrbN+P1 t9jZZKoq8s2WvEtVpghjbQAxCf/tUFx5zSfWf4MbuduaTtM119EkaSoROWvjIaId Aj57uYO8cm7/bGNEMQ3k =YsCa -----END PGP SIGNATURE----- Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC defconfig updates from Olof Johansson: "As usual, a bunch of commits, mostly adding drivers and other options to defconfigs because it makes sense to have them enabled on various development or product boards.

ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents. There's a huge number of changes here, and it's challenging to give a crisp overview of just what is in here.

ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6
and ARMv7 platforms together such that they can all be enabled and
boot the same kernel. It has been a tremendous amount of cleanup and
refactoring by a huge number of people, and creation of several new
(and major) subsystems to better abstract out all the platform details
in an appropriate manner.
The bulk of this branch is a large patchset from Arnd that brings several
of the more minor and older platforms we have closer to multiplatform
support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview
Much of this is moving around header files from old mach directories,
but there are also some cleanup patches of debug_ll (lowlevel debug
per-platform options) and other parts.
Linus Walleij also has some patchs to clean up the older ARM Realview
platforms by finally introducing DT support, and Rob Herring has some
for ARM Versatile which is now DT-only. Both of these platforms are
now multiplatform.
Finally, a couple of patches from Russell for Dove PMU, and a fix from
Valentin Rothberg for Exynos ADC, which were rebased on top of the
series to avoid conflicts.

ARM: debug-ll: fix BCM63xx entry for multiplatform
During my randconfig build testing, I found that a kernel with
DEBUG_AT91_UART and ARCH_BCM_63XX fails to build:
arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror]
It turns out that the DEBUG_UART_BCM63XX option is enabled whenever
the ARCH_BCM_63XX is, and that breaks multiplatform kernels because
we then end up using the UART address from BCM63XX rather than the
one we actually configured (if any).
This changes the BCM63XX options to only have one Kconfig option,
and only enable that if the user explicitly turns it on.

ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHz
On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.
This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.

GPIO bulk updates for the v4.5 kernel cycle:
Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better reflect
the fact that this is not the GPIO struct device abstraction. We will
add that soon so this would be totallt confusing.
- It was noted that the driver .get_value() callbacks was
sometimes reporting negative -ERR values to the gpiolib core, expecting
them to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than zero"
to indicate that a line was active. As some would have bit 31 set to
indicate "line active" it clashed with negative error codes. This is
fixed by the largeish series clamping values in all drivers with
!!value to [0,1] and then augmenting the code to propagate error codes
to consumers. (Includes some ACKed patches in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of() design
pattern is indeed very nice, but we want to reform the struct gpio_chip
to be a non-volative, stateless business, and keep states internal to
the gpiolib to be able to hold on to the state when adding a proper
userspace ABI (character device) further down the road. To achieve this,
drivers need a handle at the internal state that is not dependent on
their struct gpio_chip() so we add gpiochip_add_data() and
gpiochip_get_data() following the pattern of many other subsystems.
All the "use gpiochip data pointer" patches transforms drivers to this
scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that removed.
Instead of having a separate mm_gpio_chip struct for these generic
drivers, merge that into struct gpio_chip, simplifying the code and
removing the need for separate and confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from the
OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but
the branch is merged here too to account for infrastructural changes).
- The sx150x driver now supports the sx1502.

Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for v4.5.
Notably there are big refactorings mostly by myself, aimed at getting
the gpio_chip into a shape that makes me believe I can proceed to
preserve state for a proper userspace ABI (character device) that has
already been proposed once, but resulted in the feedback that I need
to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()
callback) and had to fix it. Also, refactored generic GPIO to be
simpler.
Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was
responsible for so much...
Apart from that we're churning along as usual.
I took some effort to test and retest so it should merge nicely and we
shook out a couple of bugs in -next.
Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better

sound updates for 4.5-rc1
We've had quite busy weeks in this cycle. Looking at ALSA core, the
significant changes are a few fixes wrt timer and sequencer ioctls
that have been revealed by fuzzer recently. Other than that, ASoC
core got a few updates about DAI link handling, but these are rather
straightforward refactoring.
In drivers scene, ASoC received quite lots of new drivers in addition
to bunch of updates for still ongoing Intel Skylake support and
topology API. HD-audio gained a new HDMI/DP hotplug notification via
component. FireWire got a pile of code refactoring/updates with
SCS.1x driver integration.
More highlights are shown below.
[NOTE: this contains also many commits for DRM. This is due to the
pull of drm stable branch into sound tree, as the base of i915 audio
component work for HD-audio. The highlights below don't contain
these DRM changes, as these are supposed to be pulled via drm tree in
anyway sooner or later.]
Core
- Handful fixes to harden ALSA timer and sequencer ioctls against
races reported by syzkaller fuzzer
- Irq description string can be unique to each card; only for
HD-audio for now
ASoC
- Conversion of the array of DAI links to a list for supporting
dynamically adding and removing DAI links
- Topology API enhancements to make everything more component based
and being able to specify PCM links via topology
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production; we really need to get to the
point where that can be done
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come
- Lots of new features and cleanups for the Renesas drivers
- ANC support for WM5110
- New drivers: Imagination Technologies IPs, Atmel class D speaker,
Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
- Rename PCM1792a driver to be generic pcm179x
HD-Audio
- Use audio component for i915 HDMI/DP hotplug handling
- On-demand binding with i915 driver
- bdl_pos_adj parameter adjustment for Baytrail controllers
- Enable power_save_node for CX20722; this shouldn't lead to
regression, hopefully
- Kabylake HDMI/DP codec support
- Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
machines
- A few code refactoring
FireWire
- Lots of code cleanup and refactoring
- Integrate the support of SCS.1x devices into snd-oxfw driver;
snd-scs1x driver is obsoleted
USB-audio
- Fix possible NULL dereference at disconnection
- A regression fix for Native Instruments devices
Misc
- A few code cleanups of fm801 driver

The clk framework and driver changes for 4.5 look pretty typical. The
bulk of the changes are to clk controller drivers, though some improvements to the core and some re-usable blocks/templates also received some love. In this past cycle the clk maintainers developed a good workflow for handling the common case of patch submissions containing a new drivers, new shared Device Tree header and a new Device Tree binding description.

kvm: rename pfn_t to kvm_pfn_t
To date, we have implemented two I/O usage models for persistent memory, PMEM (a persistent "ram disk") and DAX (mmap persistent memory into userspace). This series adds a third, DAX-GUP, that allows DAX mappings to be the target of direct-i/o. It allows userspace to coordinate DMA/RDMA from/to persistent memory. The implementation leverages the ZONE_DEVICE mm-zone that went into 4.3-rc1 (also discussed at kernel summit) to flag pages that are owned and dynamically mapped by a device driver. The pmem driver, after mapping a persistent memory range into the system memmap via devm_memremap_pages(), arranges for DAX to distinguish pfn-only versus page-backed pmem-pfns via flags in the new pfn_t type. The DAX code, upon seeing a PFN_DEV+PFN_MAP flagged pfn, flags the resulting pte(s) inserted into the process page tables with a new _PAGE_DEVMAP flag. Later, when get_user_pages() is walking ptes it keys off _PAGE_DEVMAP to pin the device hosting the page range active. Finally, get_page() and put_page() are modified to take references against the device driver established page mapping. Finally, this need for "struct page" for persistent memory requires memory capacity to store the memmap array. Given the memmap array for a large pool of persistent may exhaust available DRAM introduce a mechanism to allocate the memmap from persistent memory. The new "struct vmem_altmap *" parameter to devm_memremap_pages() enables arch_add_memory() to use reserved pmem capacity rather than the page allocator. This patch (of 18): The core has developed a need for a "pfn_t" type [1]. Move the existing pfn_t in KVM to kvm_pfn_t [2].

mm: differentiate page_mapped() from page_mapcount() for compound pages
Let's define page_mapped() to be true for compound pages if any sub-pages of the compound page is mapped (with PMD or PTE). On other hand page_mapcount() return mapcount for this particular small page. This will make cases like page_get_anon_vma() behave correctly once we allow huge pages to be mapped with PTE. Most users outside core-mm should use page_mapcount() instead of page_mapped(). Signed-off-by: Kirill A.

libnvdimm for 4.5
1/ Media error handling: The 'badblocks' implementation that originated
in md-raid is up-levelled to a generic capability of a block device.
This initial implementation is limited to being consulted in the pmem
block-i/o path. Later, 'badblocks' will be consulted when creating
dax mappings.
2/ Raw block device dax: For virtualization and other cases that want
large contiguous mappings of persistent memory, add the capability to
dax-mmap a block device directly.
3/ Increased /dev/mem restrictions: Add an option to treat all io-memory
as IORESOURCE_EXCLUSIVE, i.e. disable /dev/mem access while a driver is
actively using an address range. This behavior is controlled via the
new CONFIG_IO_STRICT_DEVMEM option and can be overridden by the
existing "iomem=relaxed" kernel command line option.
4/ Miscellaneous fixes include a 'pfn'-device huge page alignment fix,
block device shutdown crash fix, and other small libnvdimm fixes.

MTD updates for v4.5:
Generic MTD
* populate the MTD device 'of_node' field (and get a proper 'of_node' symlink
in sysfs)
- This yielded some new helper functions, and changes across a variety of
drivers
* partitioning cleanups, to prepare for better device-tree based partitioning
in the future
- Eliminate a lot of boilerplate for drivers that want to use OF-based
partition parsing
- The DT bindings for this didn't settle yet, so most non-cleanup portions
are deferred for a future release
NAND
* embed a struct mtd_info inside struct nand_chip
- This is really long overdue; too many drivers have to do the same silly
boilerplate to allocate and link up two "independent" structs, when in
fact, everyone is assuming there is an exact 1:1 relationship between a
NAND chips struct and its underlying MTD. This aids improved helpers and
should make certain abstractions easier in the future.
- Also causes a lot of churn, helped along by some automated code
transformations
* add more core support for detecting (and "correcting") bitflips in erased
pages; requires opt-in by drivers, but at least we kill a few bad
implementations and hopefully stave off future ones

Pull MTD updates from Brian Norris:
"Generic MTD:
- populate the MTD device 'of_node' field (and get a proper 'of_node'
symlink in sysfs)
This yielded some new helper functions, and changes across a
variety of drivers
- partitioning cleanups, to prepare for better device-tree based
partitioning in the future
Eliminate a lot of boilerplate for drivers that want to use
OF-based partition parsing
The DT bindings for this didn't settle yet, so most non-cleanup
portions are deferred for a future release
NAND:
- embed a struct mtd_info inside struct nand_chip
This is really long overdue; too many drivers have to do the same
silly boilerplate to allocate and link up two "independent"
structs, when in fact, everyone is assuming there is an exact 1:1
relationship between a NAND chips struct and its underlying MTD.
This aids improved helpers and should make certain abstractions
easier in the future.
Also causes a lot of churn, helped along by some automated code
transformations
- add more core support for detecting (and "correcting") bitflips in
erased pages; requires opt-in by drivers, but at least we kill a
few bad implementations and hopefully stave off future ones
- pxa3xx_nand: cleanups, a few fixes, and PM improvements
- new JZ4780 NAND driver
SPI NOR:
- provide default erase function, for controllers that just want to
send the SECTOR_ERASE command directly

Power management and ACPI updates for v4.5-rc1
- Add a debugfs-based interface for interacting with the ACPICA's
AML debugger introduced in the previous cycle and a new user
space tool for that, fix some bugs related to the AML debugger
and clean up the code in question (Lv Zheng, Dan Carpenter,
Colin Ian King, Markus Elfring).
- Update ACPICA to upstream revision 20151218 including a number
of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng,
Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box,
Rafael Wysocki).
In particular, the previously added erroneous support for the
_SUB object is dropped, the concatenate operator will support
all ACPI objects now, the Debug Object handling is improved,
the SuperName handling of parameters being control methods is
fixed, the ObjectType operator handling is updated to follow
ACPI 5.0A and the handling of CondRefOf and RefOf is updated
accordingly, module-level code will be executed after loading
each ACPI table now (instead of being run once after all tables
containing AML have been loaded), the Operation Region handlers
management is updated to fix some reported problems and a the
ACPICA code in the kernel is more in line with the upstream
now.
- Update the ACPI backlight driver to provide information on
whether or not it will generate key-presses for brightness
change hotkeys and update some platform drivers (dell-wmi,
thinkpad_acpi) to use that information to avoid sending double
key-events to users pace for these, add new ACPI backlight
quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht).
- Improve the ACPI handling of interrupt GPIOs (Christophe Ricard).
- Fix the handling of the list of device IDs of device objects
found in the ACPI namespace and add a helper for checking if
there is a device object for a given device ID (Lukas Wunner).
- Change the logic in the ACPI namespace scanning code to create
struct acpi_device objects for all ACPI device objects found in
the namespace even if _STA fails for them which helps to avoid
device enumeration problems on Microsoft Surface 3 (Aaron Lu).
- Add support for the APM X-Gene ACPI I2C device to the ACPI
driver for AMD SoCs (Loc Ho).
- Fix the long-standing issue with the DMA controller on Intel
SoCs where ACPI tables have no power management support for
the DMA controller itself, but it can be powered off automatically
when the last (other) device on the SoC is powered off via ACPI
and clean up the ACPI driver for Intel SoCs (acpi-lpss) after
previous attempts to fix that problem (Andy Shevchenko).
- Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King,
Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki,
Sinan Kaya).
- Update the device properties framework for better handling of
built-in properties, add support for built-in properties to
the platform bus type, update the MFD subsystem's handling
of device properties and add support for passing default
configuration data as device properties to the intel-lpss MFD
drivers, convert the designware I2C driver to use the unified
device properties API and add a fallback mechanism for using
default built-in properties if the platform firmware fails
to provide the properties as expected by drivers (Andy Shevchenko,
Mika Westerberg, Heikki Krogerus, Andrew Morton).
- Add new Device Tree bindings to the Operating Performance Points
(OPP) framework and update the exynos4412 DT binding accordingly,
introduce debugfs support for the OPP framework (Viresh Kumar,
Bartlomiej Zolnierkiewicz).
- Migrate the mt8173 cpufreq driver to the new OPP bindings
(Pi-Cheng Chen).
- Update the cpufreq core to make the handling of governors
more efficient, especially on systems where policy objects
are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki).
- Fix cpufreq governor handling on configurations with
CONFIG_HZ_PERIODIC set (Chen Yu).
- Clean up the cpufreq core code related to the boost sysfs knob
support and update the ACPI cpufreq driver accordingly (Rafael
Wysocki).
- Add a new cpufreq driver for ST platforms and corresponding
Device Tree bindings (Lee Jones).
- Update the intel_pstate driver to allow the P-state selection
algorithm used by it to depend on the CPU ID of the processor it
is running on, make it use a special P-state selection algorithm
(with an IO wait time compensation tweak) on Atom CPUs based on
the Airmont and Silvermont cores so as to reduce their energy
consumption and improve intel_pstate documentation (Philippe
Longepe, Srinivas Pandruvada).
- Update the cpufreq-dt driver to support registering cooling
devices that use the (P * V^2 * f) dynamic power draw formula
where V is the voltage, f is the frequency and P is a constant
coefficient provided by Device Tree and update the arm_big_little
cpufreq driver to use that support (Punit Agrawal).
- Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq,
blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia,
Jacob Tanenbaum, Markus Elfring).
- cpuidle core tweaks related to polling and measured_us
calculation (Rik van Riel).
- Removal of modularity from a few cpuidle drivers (clps711x,
ux500, exynos) that cannot be built as modules in practice
(Paul Gortmaker).
- PM core update to prevent devices from being probed during
system suspend/resume which is generally problematic and may
lead to inconsistent behavior (Grygorii Strashko).
- Assorted updates of the PM core and related code (Julia Lawall,
Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki,
Ulf Hansson).
- PNP bus type updates (Christophe Le Roy, Heiner Kallweit).
- PCI PM code cleanups (Jarkko Nikula, Julia Lawall).
- cpupower tool updates (Jacob Tanenbaum, Thomas Renninger).

Pull oower management and ACPI updates from Rafael Wysocki:
"As far as the number of commits goes, ACPICA takes the lead this time,
followed by cpufreq and the device properties framework changes.
The most significant new feature is the debugfs-based interface to the
ACPICA's AML debugger added in the previous cycle and a new user space
tool for accessing it.
On the cpufreq front, the core is updated to handle governors more
efficiently, particularly on systems where a single cpufreq policy
object is shared between multiple CPUs, and there are quite a few
changes in drivers (intel_pstate, cpufreq-dt etc).
The device properties framework is updated to handle built-in (ie
included in the kernel itself) device properties better, among other
things by adding a fallback mechanism that will allow drivers to
provide default properties to be used in case the plaform firmware
doesn't provide the properties expected by them.
The Operating Performance Points (OPP) framework gets new DT bindings
and debugfs support.
A new cpufreq driver for ST platforms is added and the ACPI driver for
AMD SoCs will now support the APM X-Gene ACPI I2C device.
The rest is mostly fixes and cleanups all over.
Specifics:
- Add a debugfs-based interface for interacting with the ACPICA's AML
debugger introduced in the previous cycle and a new user space tool

Pull arm[64] perf updates from Will Deacon:
"In the past, I have funnelled perf updates through the respective
architecture trees, but now that the arm/arm64 perf driver has been
largely consolidated under drivers/perf/, it makes more sense to send
a separate pull, particularly as I'm listed as maintainer for all the
files involved. I offered the branch to arm-soc, but Arnd suggested
that I just send it to you directly.
So, here is the arm/arm64 perf queue for 4.5. The main features are
described below, but the most useful change is from Drew, which
advertises our architected event mapping in sysfs so that the perf
tool is a lot more user friendly and no longer requires the use of
magic hex constants for profiling common events.

ARM: dts: Fix omap5 PMIC control lines for RTC writes
The palmas PMIC has two control lines that need to be muxed properly for things to work. The sys_nirq pin is used for interrupts, and msecure pin is used for enabling writes to some PMIC registers. Without these pins configured properly things can fail in mysterious ways. For example, we can't update the RTC registers on palmas PMIC unless the msecure pin is configured. And this is probably the reason why we had RTC missing from the omap5 dts file. According to "OMAP5430 ES2.0 Data Manual [Public] VErsion A (Rev. F)" swps052f.pdf, mux mode 1 is for sys_drm_msecure so in theory there's should be no need to configure it as a GPIO pin. However, it seems there are some reliability issues using the msecure mux mode. And the TI trees configure the msecure pin as GPIO out high instead. As the PMIC only cares that the msecure line is high to allow access to the RTC registers, let's use a GPIO hog as suggested by Nishanth Menon <nm@ti.com>. Also the use of the internal pull was considered but supposedly that may not be capable of keeping the line high in a noisy environment. If we ever see high security omap5 products in the mainline tree, those need to skip the msecure pin muxing and ignore setting the GPIO hog. Chances are the related pin mux registers are locked in that case and the msecure pin is managed by whatever software may be running in the ARM TrustZone. Who knows what the original intention of the msecure pin was. Maybe it was supposed to prevent the system time to be set back for some game demo modes to time out? Anyways, it seems that later PMICs like tps659037 have recycled this pin for "powerhold" and devices like beagle-x15 do not need changes to the msecure pin configuration. To avoid further confusion with TWL variant PMICs, beagle-x15 does not have a back-up battery for RTC palmas. Instead the mcp79410 RTC is used with rtc-ds1307 driver. There is a "powerhold" jumper j5 holes near the palmas PMIC, and shorting it seems to power up beagle-x15 automatically. It is unknown if it also has other side effects to the beagle-x15 power up sequence. Cc: stable@vger.kernel.org # v4.4 Signed-off-by: Tony Lindgren <tony@atomide.com> |

Last minute urgent pull request to prevent file system corruption
on Nokia N900. Looks like we have a GPMC bus timing bug that has gone unnoticed because of bootloader configured registers until few days ago. We are not detecting the onenand clock rate properly unless we have CONFIG_OMAP_GPMC_DEBUG set and this causes onenand corruption that can be easily be reproduced. There seems to be also an additional bug still lurking around for onenand corruption. But that is still being investigated and it does not seem to be GPMC timings related. Meanwhile, it would be good to get this fix into v4.4 to prevent wrong timings from corrupting onenand. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWj+LZAAoJEBvUPslcq6VzRwMQAN9cxwbGblHuEnt22GJEQNUP XRgAB6j00zKugAYg5QCXihZf+SgQuvI8VeB+BeI0K0vL0zNnLlF/jiKYg1fwzDvr jcKx8dKbcfI7idWtNP2DL1nWe9dDjT+hBye3xH/DavXFcvFiuMLrBtbZ2WO1zPn7 MYADo5jh+X3/Cl+9okS0q7ZblaZ+txs+8dl87bIkup96A2hYw/Zp+h4H7PcnJbFn 4YyOVMsHwTUeCXCbcd5aDZvENN4uhXYFZXo1glrB4GePz7F7ST+vgUZkhuSqI4Z0 vwRpYPjLtZfsvW9SWodMLt7r7qIKYbEX7ATtjYIV2QLa8QL14KUZLFk35VgXGCA5 WciP3UeNQrzQPUSnDfthYDVDWV50EbrN0Tw3/f+xo4RDGYfMZ5A26jZsJavHaEHj stB0EGy72RkqUJmCqquP3X2k1W2JsFbhI/WKyHxZspOuvadFzbfW5Rz8I1ad6+68 b485s5qPLYpufZj5+03wAnuCJBVz8A6x6qAZqi2sIaHbqa8H0b0/u85Svrfe0y45 PxxwLbjipWy2/FCTicJL3HiboSGdJoXXO6ru65oEqG7J6BFGk/607QCSpEB3FWbW jx/4WbdMcsoPgqlbFoCG5TSPD7esMdhBNlZirZiAvRoPeSdmQVOy230dLn7Cek7z 3ws+XPHWsOSgATpwvE// =QtBl -----END PGP SIGNATURE----- Merge tag 'omap-for-v4.4/onenand-corruption' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes Pull "urgent onenand file system corruption fix for n900" from Tony Lindgren: Last minute urgent pull request to prevent file system corruption on Nokia N900.

ARM: multi_v7_defconfig: Add rockchip audio support
As the rockchip SPDIF driver landed for 4.4 and the required clock patches to make it work properly are scheduled for the 4.5 merge window it seems time to support for audio device found on rockchip boards in the defconfig as well.

arm: multi_v7_defconfig: Add virtio drivers
To make multi_v7_defconfig really "multi", let's add virtio drivers to allow booting a default kernel as a KVM/QEMU guest. MACH_VIRT is already defined, so we just add VIRTIO_BLK, VIRTIO_NET and VIRTIO_CONSOLE to actually make this kernel useful in a guest.

ARM: versatile: add the syscon LEDs to the DT
The device tree version of Versatile AP/PB never had LED support so we are missing LEDs from our hardware boards. Add this as syscon LEDs like we did for Integrator and Juno. We need to spawn devices in the syscon with "simple-mfd" for this to work. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de> |

ARM: versatile: enable the right LEDs
The Versatile now only has device tree boot support, and the device tree version does not support CONFIG_LEDS_VERSATILE. Instead select CONFIG_LEDS_SYSCON and MFD_SYSCON, so we can get LEDs support from the same generic driver that drives most other ARM reference boards.

ARM: pxa: add defconfig covering all the boards
Add a defconfig covering all known pxa board, ie. all selectable machine
files in arch/arm/mach-pxa/*.c.
This defconfig was built by doing :
- aggregation of all known defconfigs by cat
am200epdkit_defconfig
cm_x2xx_defconfig
cm_x300_defconfig
colibri_pxa270_defconfig
colibri_pxa300_defconfig
corgi_defconfig
em_x270_defconfig
eseries_pxa_defconfig
ezx_defconfig
h5000_defconfig
imote2_defconfig
lpd270_defconfig
lubbock_defconfig
magician_defconfig
mainstone_defconfig
multi_v7_defconfig
palmz72_defconfig
pcm027_defconfig
pxa255-idp_defconfig
pxa3xx_defconfig
raumfeld_defconfig
spitz_defconfig
trizeps4_defconfig
viper_defconfig
xcep_defconfig
zeus_defconfig
- manual make menuconfig to ensure :
- all pxa implementation were selected
- all drivers were transformed into modules rather than builtin
=> as a consequence this single kernel will rely on an initramfs
=> as kernel size matters on pxa, each machine can take the subset
of modules required for it to work
- all missed configurations are selected verified by :
=> grep -i pxa .config | grep "is not set"
=> this should only show the left on purpose options (either not
selectable or sharpsl exception below)
- CONFIG_PXA_SHARPSL was disabled
This breaks the boot very early on any non Sharp platform, see
head-sharpsl.S
This defconfig was tested as booting up to the login phase on :
- lubbock (pxa25x)
- mainstone (pxa27x)
- zylonite (pxa3xx)
The completion of this work will require to :
- parse manually all the arch/arm/mach-pxa/*c files, look for all
platform devices added, and verify they are all in pxa_defconfig
- do the same to ensure all pxa specific drivers (leds, gpio, ...) are
included
