This updates the Versatile defconfig to:
- Use NO_HZ_IDLE and HIGH_RES_TIMERS
- Enable the I2C driver
- Enable the SPI driver
- Enable the RTC driver for DS1338 as found on the Versatile
boards
- Compile in the MMCI MMC driver, which is good if you
want to mount a root FS on the MMC card without having
to first load this module from an initramfs
Patch tested on the Versatile AB, QEMU for Versatile AB
and QEMU for Versatile PB.

The Nomadik has sporadic crashes because of these latencies, setting
them to max makes the platform work nicely, so use this values for
now.
These latencies were set to 2 since the Nomadik platform was merged,
but I suspect they never took effect until the right size and
associativity for the cache was specified in the device tree and
that is why the crash comes now.

Commit 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")
unified the GPMC debug for the SoCs with GPMC. The commit also left out
the option for HWMOD_INIT_NO_RESET as we now require proper timings for
GPMC to be able to remap GPMC devices out of address 0.
Unfortunately on Nokia N900, onenand now only partially works with the
device tree provided timings. It works enough to get detected but the
clock rate supported by the onenand chip gets misdetected. This in turn
causes the GPMC timings to be miscalculated and this leads into file
system corruption on N900.
Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync
write. This is needed also for async timings when we write to onenand
with omap2_onenand_set_async_mode(). Without sync write bit set, the
async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff.
Let's exit with an error if onenand rate is not detected. And let's
remove the extra call to omap2_onenand_set_async_mode() as we only need
to do this once at the end of omap2_onenand_setup_async().

The separate struct bgpio_chip has been a pain to handle, both
by being confusingly similar in name to struct gpio_chip and
for being contained inside a struct so that struct gpio_chip
is contained in a struct contained in a struct, making several
steps of dereferencing necessary.
Make things simpler: include the fields directly into
<linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and
get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix
some of the member variables with bgpio_* and add proper
kerneldoc while we're at it.
Modify all users to handle the change and use a struct
gpio_chip directly. And while we're at it: replace all
container_of() dereferencing by gpiochip_get_data() and
registering the gpio_chip with gpiochip_add_data().

This implements UEFI kernel support for 32-bit ARM, based on the existing
arm64 support and existing generic early ioremap support. It is based on
commit f7d9248942 ("arm64/efi: refactor EFI init and runtime code for
reuse by 32-bit ARM"), which was pulled from the arm64 repo [1] as branch
'aarch64/efi'
[1] git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux.git
The PJ4 inline asm sequence to write to cp15 cannot be built in Thumb-2
mode, due to the way it performs arithmetic on the program counter, so it
is built in ARM mode instead. However, building C files in ARM mode under
CONFIG_THUMB2_KERNEL is problematic, since the instrumentation performed
by subsystems like ftrace does not expect having to deal with interworking
branches.
Since the sequence in question is simply a poor man's ISB instruction,
let's use a straight 'isb' instead when building in Thumb2 mode. Thumb2
implies V7, so 'isb' should always be supported in that case.

Commit 69fb4dcada ("power: Add an axp20x-usb-power driver") introduced a new

the driver was not added to sunxi_defconfig which breaks USB support for some
boards (e.g. LeMaker BananaPi) as the kernel will now turn off the USB power
supply during boot by default if the driver isn't present. (This was not the
case in linux 4.3 or lower where the USB power was always left on.)
Hence, add the driver to sunxi_defconfig in order to keep USB support working
on those boards that require it.

Merge "DaVinci device-tree updates for v4.5" from Sekhar Nori:
EDMA device-tree updates including move to
new EDMA bindings and EDMA support for MMC/SD
and SPI.
* tag 'davinci-for-v4.5/dts' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
ARM: DTS: da850: Enable DMA for SPI1

related to dm814x, just the clocks are a bit different and it has a
different set of integrated devices. And let's get some basic dm814x
and dra62x devices working as many of the devices are like on am33xx::
- pinctrl using the pinctrl defines as for am33xx
- Updated EDMA bindings with support for using exma_xbar
- MMC support for dm814x-evm, t410 and dra62x-j5eco-evm
- USB support for dm814x-evm, t410 and dra62x-j5eco-evm
This branch depends on an earlier omap-for-v4.5/81xx-fixes-signed
branch that has dm814x dts fixes interlaced with SoC related fixes to
keep things booting. The interlaced SoC and dts fixes were needed
because of issues with the device tree defined clocks that just
happened to work on bootloader timings for t410 earlier.

versatile_defconfig has not been a reasonable default for a very long

based on an old ARM926 CPU core.
This changes the default to multi_v7_defconfig, which is much more
relevant to anyone doing a build test on ARM, as it covers a wide
range of platforms.

DWC3 device found on Exynos SoCs cannot work in OTG mode alone, because
it lacks some OTG related control part. OTG mode operation is possible
only with external hardware logic (usually GPIO-based) specific to
the board. Right now, however, there is no driver for such logic and no
bindings, so the OTG mode is dysfunctional at all (this means that it
doesn't work as a peripheral nor as a host). This patch sets the operation
mode to peripheral to get DWC3_1 device at least somehow working. This can
be later updated, when proper OTG driver and bindings get developed.

Switch to use the ti,edma3-tpcc and ti,edma3-tptc binding for the eDMA3.
With the new bindings boards can customize and tweak the DMA channel
priority to match their needs. With the new binding the memcpy is safe
to be used since with the old binding it was not possible for a driver
to know which channel is allowed to be used as non HW triggered channel.
Using the new binding will allow us to reserve PaRAM slots to be used by
the DSP which was not possible before and prevented the da850 boards to be
moved to DT only.
Note that the DMA memcpy is disabled, it can be enabled by reserving
channels for memcpy by adding the following property to the edma node:
ti,edma-memcpy-channels = <20 21>; /* Reserving channel 20 and 21 for memcpy */

Enabling CPUFreq support for Tegra124 Chromebooks is causing the Tegra124
to hang when resuming from suspend.
When CPUFreq is enabled, the CPU clock is changed from the PLLX clock to
the DFLL clock during kernel boot. When resuming from suspend the CPU
clock is temporarily changed back to the PLLX clock before switching back
to the DFLL. If the DFLL is operating at a much lower frequency than the
PLLX when we enter suspend, and so the CPU voltage rail is at a voltage
too low for the CPUs to operate at the PLLX frequency, then the device
will hang.
Please note that the PLLX is used in the resume sequence to switch the CPU
clock from the very slow 32K clock to a faster clock during early resume
to speed up the resume sequence before the DFLL is resumed.
Ideally, we should fix this by setting the suspend frequency so that it
matches the PLLX frequency, however, that would be a bigger change. For
now simply disable CPUFreq support for Tegra124 Chromebooks to avoid the
hang when resuming from suspend.

Chromebooks")

We can boot dra62x j5-eco using the dm814x code as the clocks and
devices are mapped in the device tree. The dra62x is also known
as jacinto 5 eco.
We may want to add separate soc_is macros for dra62x if needed,
but this gets us to the point where we can boot dra62x with just
dts changes.
Let's also print out the unknown hawkeye register to make things
a bit easier for new SoC variants.

The io-domain driver is necessary to notify the soc about voltages changes
happening on supplying regulators. Probably the most important user right
now is the mmc tuning code, where the soc needs to get notified when the
voltage is dropped to the 1.8V point.
As this option is necessary to sucessfully tune UHS cards etc, it should
get built in.

change the omap initcall levels a bit to initialize things later to allow
early device drivers at core_initcall level. This makes things easier
for us as most clocks can be made into regular device drivers except for
a few early clocks needed to initialize system timers. I wanted to have
these changes sit in Linux next for a few weeks before sending out a pull
request, and so far now issues have showed up.
The other changes in this series are timer changes for making use of the
new PWM driver, and timer changes to support more high security SoCs.
Also few minor improvments for module autoidle settings for ti81xx spinbox
and dra7 debug on uart4 in hwmod code. The rest is pretty much just removal
of platform data for SoCs that are all device tree only nowadays.

CPU_IDLE and ARM TWD timer. This is probably a common configuration setup
for people making products with these SoCs so let's make sure it works.
Also a wakeirq fix for duovero parlor making my life a bit easier as that
allows me to run basic PM regression tests on it.
It would be nice to have these in v4.4, but if it gets too late for that
because of the holidays, it is not super critical if these get merged for
v4.5.

Merge tag 'omap-for-v4.4/fixes-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
Few fixes for omaps to allow am437x only builds to boot properly with
CPU_IDLE and ARM TWD timer. This is probably a common configuration setup
for people making products with these SoCs so let's make sure it works.
Also a wakeirq fix for duovero parlor making my life a bit easier as that
allows me to run basic PM regression tests on it.
It would be nice to have these in v4.4, but if it gets too late for that
because of the holidays, it is not super critical if these get merged for
v4.5.

It's all very well providing an events directory to userspace that
details our events in terms of "event=0xNN", but if we don't define how
to encode the "event" field in the perf attr.config, then it's a waste

This patch adds a single format entry to describe that the event field
occupies the bottom 8 bits of our config field on ARMv7.

Previously, the device tree mapped the FPGA like any other IPs inside
the SoC, but it is actually mapped through the WEIM (Wireless External
Interface Module). This patch updates the device tree to make use of it.
About the timings: in the image provided by the manufacturer, only
CS0GCR1 is changed. The other values are the default ones, but the WEIM
bindings expect them to be all explicitly set in the device tree, so I
just put the default values in the dt.

Move the LVDS clock parent to PLL3_USB_OTG, so that HDMI and LVDS can be

According to commit 2503a5ecd8
"ARM: 6201/1: RealView: Do not use outer_sync() on ARM11MPCore
boards with L220" Some PB11MPCore RealView core tiles have broken
outer_sync.
We got rid of the custom barriers from the machine by disabling
outer sync, but that was just for the boardfile case. We have
to be able to do the same in the device tree case.
Since __l2c_init() is cloning and copying the L2C vtable,
we pass an argument to this function to optionally numb
the outer sync operation if desired, before initializing
the cache.
After this we can set up the cache correctly on the RealView
PB11MPCore. This was tested on a PB11MPCore known to have the
issue. Before this, spurious crashes would occur if we try to
set up the cache properly, after this it boots rock solid.

Having IPI_CPU_BACKTRACE as SGI15 may not work if the kernel is
running in non-secure mode and that the secure firmware has
decided to follow ARM's recommendations that SGI8-15 should
be reserved for secure purpose.
Now that we are "only" using SGI0-6, change IPI_CPU_BACKTRACE
to use SGI7, which makes it more likely to work.

Since 9a46ad6d6d ("smp: make smp_call_function_many() use logic
similar to smp_call_function_single()"), the core IPI handling
has been simplified, and generic_smp_call_function_interrupt is
now the same as generic_smp_call_function_single_interrupt.
This means that one of IPI_CALL_FUNC and IPI_CALL_FUNC_SINGLE has
become redundant. We can then safely drop IPI_CALL_FUNC_SINGLE,
and use only IPI_CALL_FUNC.
This has the advantage of reducing the number of SGI IDs we're using
(a fairly scarse resource).
Tested on a dual A7 board.

The suspend() hook in the cpuidle_ops struct is always called on
the cpu entering idle, which means that the cpu parameter passed
to the suspend hook always corresponds to the local cpu, making
it somewhat redundant.
This patch removes the logical cpu parameter from the ARM
cpuidle_ops.suspend hook and updates all the existing kernel
implementations to reflect this change.

Merge tag 'realview-multiplatform-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/multiplatform
Pull "Multiplatform support for the RealView" from Linus Walleij:
Here is the result of my application of the second part of Arnds
patchset, actually enabling multiplatform and getting the RealView
off the ground as a multiplatform target.
It is dependent on an outstanding patch to the irqchips tree bumping
the number of GICs to 2 for the RealView platform. I cannot say I will
be sleepless if these go in side by side: each branch will compile but
will not boot until both trees have been pulled hurting bisectability a
bit.

Before commit 662d971584
("arm/arm64: KVM: Kill CONFIG_KVM_ARM_{VGIC,TIMER}") is was possible to
compile the kernel without vGIC and vTimer support. Commit message says
about possibility to detect vGIC support in runtime, but this has never
been implemented.
This patch introduces runtime check, restoring the lost functionality.
It again allows to use KVM on hardware without vGIC. Interrupt
controller has to be emulated in userspace in this case.
-ENODEV return code from probe function means there's no GIC at all.
-ENXIO happens when, for example, there is GIC node in the device tree,
but it does not specify vGIC resources. Any other error code is still
treated as full stop because it might mean some really serious problems.

David Binderman reported that the exception injection code had a
couple of unused variables lingering around.
Upon examination, it looked like this code could do with an
anticipated spring cleaning, which amounts to deduplicating
the CPSR/SPSR update, and making it look a bit more like
the architecture spec.
The spurious variables are removed in the process.

System will misbehave in the following case:
- AM43XX only build (UP);
- CONFIG_CPU_IDLE=y
- ARM TWD timer enabled and selected as clockevent device.
In the above case, It's expected that broadcast timer will be used as
backup timer when CPUIdle will put MPU in low power states where ARM
TWD will stop and lose its context. But, the CONFIG_SMP might not be
selected when kernel is built for AM43XX SoC only and, as result,
GENERIC_CLOCKEVENTS_BROADCAST option will not be selected also. This
will break CPUIdle and System will stuck in low power states.
Hence, fix it by selecting GENERIC_CLOCKEVENTS_BROADCAST option for
AM43XX SoCs always and add empty tick_broadcast() function
implementation - no need to send any IPI on UP. After this change
timer1 will be selected as broadcast timer the same way as for SMP,
and CPUIdle will work properly.

Moving ARCH_VERSATILE into ARCH_MULTIPLATFORM means that it no longer
works as the default target for MMU-less kernels. While we might
want to get that working again in the future, it's also a rather
bad default, and it makes sense to make ARM_SINGLE_V7M the default
because that is what realistically all NOMMU users on ARM are using,
and it actually is what gets selected by default in the absence of
versatile in the choice statement.
Related to this, 'allnoconfig' kernels fail to link with the new
default, as they do not include a machine record:
arm-linux-gnueabi-ld: no machine record defined
For ARCH_MULTIPLATFORM kernels, we avoid this error by using a
default machine descriptor that works for all trivial platforms,
like ARCH_VIRT. The same reasoning applies for ARM_SINGLE_V7M,
as that can also boot with empty machine descriptors both on
qemu and on real hardware, as long as all the drivers are present.
We could also follow up with a patch to remove the existing
machine descriptors for the ARMv7M platforms, the only callback
pointer the four platforms contain today is the armv7m_restart
handler and we can simply make that the default for v7M with an
add-on patch.

I accidentally move the DEBUG_LL_UART_EFM32 option when sorting all

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Fixes: 1dc9341 ("ARM: debug-ll: reorder Kconfig alphanumerically")
The debug-ll infrastructure can be configured in two ways, either
by selecting a platform specific debug option, or by picking one
of the generic options (8250 or pl01x typically). For compatibility
with multiplatform kernels, we have changed a couple of platforms
to use the former method now when they used to use the latter.
Unfortunately, this broke the defconfigs because now they still
enable CONFIG_DEBUG_LL_UART_PL01X or CONFIG_DEBUG_LL_UART_8250,
and we no longer configure the correct register addresses
automatically.
Embarrassingly, this was only found in linux-next when the
defconfig builds turned up errors for multiple people, and I
had not caught those in my own tests, which were done using
the randconfig fixes patchset on top, and that has a workaround
to avoid a build error when the addresses are not configured.
The error was something like:
.config:2010:warning: symbol value '' invalid for DEBUG_UART_PHYS
.config:2011:warning: symbol value '' invalid for DEBUG_UART_VIRT
This patch avoids the problem by removing the respective
statements from the defconfig files. Any out of tree defconfig
files on the platforms I have changed will have to do the same
change or run into the build error above. Any users that have
a full .config already set the correct DEBUG_UART_PHYS/VIRT
addresses and do not need to change anything.

The ARM compiler inserts calls to __aeabi_idiv() and
__aeabi_uidiv() when it needs to perform division on signed and
unsigned integers. If a processor has support for the sdiv and
udiv instructions, the kernel may overwrite the beginning of those
functions with those instructions and a "bx lr" to get better
performance.
To ensure that those functions are aligned to a 32-bit word for easier
patching (which might not always be the case in Thumb mode) and that
the two patched instructions end up in the same cache line, a 8-byte
alignment is enforced when ARM_PATCH_IDIV is selected.
This was heavily inspired by a previous patch from Stephen Boyd.

The proc-v7.S code uses a small temporary stack to preserve register
content in its setup code. This stack is located in the .text section
which is normally meant to be read-only.
Move that temporary stack to the .bss section and get its address in
a position independent way, similarly to what we do in other parts
of the kernel.
While at it, one comments was updated to reflect reality, and the list
of saved registers in the proc-v7.S case is updated to match the comment
next to it for coherency.
