The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").
These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:

Commit d20f997b4d ("ARM: dts: am57xx-beagle-x15: Remove pinmux
configurations for erratum i869") fat fingered a change in which
basically replaced mmc2_pinctrl_default with mmc1_pinctrl_default. And
kernel dutifully reports conflict of usage.
[...]
pinctrl-single 4a003400.pinmux: pin 4a00376c.0 already requested by
4809c000.mmc; cannot claim for 480b4000.mmc
pinctrl-single 4a003400.pinmux: pin-219 (480b4000.mmc) status -22
pinctrl-single 4a003400.pinmux: could not request pin 219 (4a00376c.0)
from group mmc1_pins_default on device pinctrl-single
omap_hsmmc 480b4000.mmc: Error applying setting, reverse things back
omap_hsmmc 480b4000.mmc: could not initialize pin control state
[...]
But, thanks to the fact that we were in fact setting all the muxes in
U-Boot, all the MMC devices were still properly detected.
Fix the typo.

1) Select is a reverse dependency and is hard for people to understand
and can sometimes be a pain to track down
2) Build coverage goes down because configs are hidden

This helps to get 100% intensity closer to "always on".
It compensates for an effect of dmtimer which at 100% still emits short
"off" impulses and the startup-time of the DC/DC converter makes
backlight intensity not reach full scale. The lower the PWM frequency
is, the smaller is this effect.

One of the last users of NO_IRQ on ARM is the switch initialization
code on orion5x, which sometimes passes a GPIO based IRQ number.
However, the driver doesn't actually use this number, and according
to Andrew Lunn never will do it for non-DT based machines, so
we can simply drop the irq argument.
Simplifying it further, we can also drop the static platform_device
and instead call platform_device_register_data(), which in turn
lets us mark the platform_data structures as __initdata and slightly
reduce the memory consumption.

For most devices, we know in advance whether they have an
interrupt line or not, so we can avoid passing NO_IRQ and
instead split fill_resources() into two interfaces, with
only the new fill_resources_irq() function taking an irq
argument, which it then can use unconditionally.

Commit 88e957d6e4 ("xen: introduce xen_vcpu_id mapping") broke SMP
ARM guests on Xen. When FIFO-based event channels are in use (this is
the default), evtchn_fifo_alloc_control_block() is called on
CPU_UP_PREPARE event and this happens before we set up xen_vcpu_id
mapping in xen_starting_cpu. Temporary fix the issue by setting direct
Linux CPU id <-> Xen vCPU id mapping for all possible CPUs at boot. We
don't currently support kexec/kdump on Xen/ARM so these ids always
match.
In future, we have several ways to solve the issue, e.g.:
- Eliminate all hypercalls from CPU_UP_PREPARE, do them from the
starting CPU. This can probably be done for both x86 and ARM and, if
done, will allow us to get Xen's idea of vCPU id from CPUID/MPIDR on
the starting CPU directly, no messing with ACPI/device tree
required.
- Save vCPU id information from ACPI/device tree on ARM and use it to
initialize xen_vcpu_id mapping. This is the same trick we currently
do on x86.

Latest update to the BeagleBoard-X15 platform (revision B1)[1] updates
for allowing UHS SD cards to function with the split of supply to SD
card from a dedicated LDO.
As a result of this, AM57xx BeagleBoard-X15 now uses gpio2_30 instead
of gpio6_28 for HDMI because HDMI_LS_OE should now be switched from
GPIO6_28(Y9) to GPIO2_30 (AG8) to avoid a 1.8V GPIO toggling a 3.3V
SoC input when the SD card is in UHS 1.8V mode.
NOTE: For UHS mode to function, we need full fledged IODelay support
in kernel to be functional. IODelay support is yet to be added.
Further, It does not make much sense to spin off a new board
compatible flag since there is no real functional benefit for the
same.
Note: Even though production version is supposed to be B1, there is
over ~200 boards of previous version (A2)[2] out there which continue
to get supported with the existing dts file (to maintain compatibility
with existing bootloaders for A2) and the production board is now
supported as revb1.

Pinmuxing for DRA7x/AM57x family of processors need to be done in IO
isolation as part of initial bootloader executed from SRAM. This is
done as part of iodelay configuration sequence and is required due
to the limitations introduced by erratum ID: i869[1] (IO Glitches
can occur when changing IO settings) and elaborated in the Technical
Reference Manual[2] 18.4.6.1.7 Isolation Requirements.
Only peripheral that is permitted for dynamic pin mux configuration
is MMC and DCAN. MMC is permitted to change to accommodate the
requirements for varied speeds (which require IO-delay support in
kernel as well). DCAN is a result of i893[1] (DCAN initialization
sequence). However, since we don't use DCAN on X15, with the exception
of MMC, all other pin mux configurations are removed from the dts.

is correct. The PMIC pad1 and 2 values for omap5-uevm and igepv5 are

Few changes to fix issues I've noticed while debugging omap5-uevm
wl18xx issues:
1. Move wlcore irq pin muxing under wlcore. This irq could be
different from gpio_wk14 on some board variants
2. Don't configure pull on wlcore irq pin. There is a 10k
pull up resistor R105 on the device to VDDS_1v8_MAIN
3. The padconf register for wlsdio_data1 is wrong, it's really
at 0x1a8 + 2 - 0x40 = 0x16a offset, not at 0x168 as that's
for wlsdio_data0
4. Mark the omap5-uevm wlan as compatible with ti,wl1837 as
that's what the TDK R078 part seems to be
5. The MMC interrupt for WLAN musb be wakeupgen, not gic
Looks like omap5-uevm WLAN behaves better now, but I still seem
to have issues with some access points.

As noted in commit 3ebee5a2e1 ("arm64: dts: kill skeleton.dtsi"),
there are a number of problems with skeleton.dtsi, and it would be
prefereable to remove it entirely. As there are a large number of
existing users, fixing these up will take a while.
This patch adds a note to arm's skeleton.dtsi noting that this is the
case, to make this more obvious and hopefully minimize new uptake of
skeleton.dtsi in the mean time.

The AES-CTR glue code avoids calling into the blkcipher API for the
tail portion of the walk, by comparing the remainder of walk.nbytes
modulo AES_BLOCK_SIZE with the residual nbytes, and jumping straight
into the tail processing block if they are equal. This tail processing
block checks whether nbytes != 0, and does nothing otherwise.
However, in case of an allocation failure in the blkcipher layer, we
may enter this code with walk.nbytes == 0, while nbytes > 0. In this
case, we should not dereference the source and destination pointers,
since they may be NULL. So instead of checking for nbytes != 0, check
for (walk.nbytes % AES_BLOCK_SIZE) != 0, which implies the former in
non-error conditions.

Currently, when running on FVP, CPU 0 boots up with its BPR changed from
the reset value. This renders it impossible to (preemptively) prioritize
interrupts on CPU 0.
This is harmless on normal systems since Linux typically does not
support preemptive interrupts. It does however cause problems in
systems with additional changes (such as patches for NMI simulation).
Many thanks to Andrew Thoelke for suggesting the BPR as having the
potential to harm preemption.

different mask. On LPAE, this lead to a wrong assumption of what
initial cache policy has been used. Later a check forces the

SA1111 PCMCIA was broken when PCMCIA switched to using dev_pm_ops for
the PCMCIA socket class. PCMCIA used to handle suspend/resume via the
socket hosting device, which happened at normal device suspend/resume
time.
However, the referenced commit changed this: much of the resume now
happens much earlier, in the noirq resume handler of dev_pm_ops.
However, on SA1111, the PCMCIA device is not accessible as the SA1111
has not been resumed at _noirq time. It's slightly worse than that,
because the SA1111 has already been put to sleep at _noirq time, so
suspend doesn't work properly.
Fix this by converting the core SA1111 code to use dev_pm_ops as well,
and performing its own suspend/resume at noirq time.
This fixes these errors in the kernel log:
pcmcia_socket pcmcia_socket0: time out after reset
pcmcia_socket pcmcia_socket1: time out after reset
and the resulting lack of PCMCIA cards after a S2RAM cycle.

Since its initial commit, the driver is buggy for multiple interrupts
handling. The translation from the former lubbock.c file was not
complete, and might stall all interrupt handling when multiple
interrupts occur.
This is especially true when inside the interrupt handler and if a new
interrupt comes and is not handled, leaving the output line still held,
and not creating a transition as the GPIO block behind would expect to
trigger another cplds_irq_handler() call.
For the record, the hardware is working as follows.
The interrupt mechanism relies on :
- one status register
- one mask register
Let's suppose the input irq lines are called :
- i_sa1111
- i_lan91x
- i_mmc_cd
Let's suppose the status register for each irq line is called :
- status_sa1111
- status_lan91x
- status_mmc_cd
Let's suppose the interrupt mask for each irq line is called :
- irqen_sa1111
- irqen_lan91x
- irqen_mmc_cd
Let's suppose the output irq line, connected to GPIO0 is called :
- o_gpio0
The behavior is as follows :
- o_gpio0 = not((status_sa1111 & irqen_sa1111) |
(status_lan91x & irqen_lan91x) |
(status_mmc_cd & irqen_mmc_cd))
=> this is a N-to-1 NOR gate and multiple AND gates
- irqen_* is exactly as programmed by a write to the FPGA
- status_* behavior is governed by a bi-stable D flip-flop
=> on next FPGA clock :
- if i_xxx is high, status_xxx becomes 1
- if i_xxx is low, status_xxx remains as it is
- if software sets status_xxx to 0, the D flip-flop is reset
=> status_xxx becomes 0
=> on next FPGA clock cycle, if i_xxx is high, status_xxx becomes
1 again

The commit 9bf448c66d ("ARM: pxa: use generic gpio operation instead of

warning:
arch/arm/mach-pxa/spitz_pm.c:172 spitz_charger_wakeup()
warn: double left shift '!gpio_get_value(SPITZ_GPIO_KEY_INT)
<< (1 << ((SPITZ_GPIO_KEY_INT) & 31))'
As Dan reported, the value is shifted three times :
- once by gpio_get_value(), which returns either 0 or BIT(gpio)
- once by the shift operation '<<'
- a last time by GPIO_bit(gpio) which is BIT(gpio)
Therefore the calculation lead to a chained or operator of :
- (1 << gpio) << (1 << gpio) = (2^gpio)^gpio = 2 ^ (gpio * gpio)
It is be sheer luck the former statement works, only because each gpio
used is strictly smaller than 6, and therefore 2^(gpio^2) never
overflows a 32 bits value, and because it is used as a boolean value to
check a gpio activation.
As the xxx_charger_wakeup() functions are used as a true/false detection
mechanism, take that opportunity to change their prototypes from integer
return value to boolean one.

It also results in some reordering of the nodes in the DTBs (the /aliases

The Cortex A9 MPCore tile can be mounted on top of the revision
D variant of the RealView EB, so create another variant of the
DTS file for this.
arm-realview-eb-a9mp = mounted on pre-revision D baseboard
arm-realview-eb-a9mp-bbrevd = mounted on the revision D baseboard
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
There used to be two versions of the RealView EB 11MPCore:
- arm-realview-eb-11mp.dts: the most common variant supported by
QEMU with the revision C core tile
- arm-realview-eb-revb.dts: for the variant with the elder revision
B core tile.
As it turns out that there are also a few variants of the
baseboard, unrelated to the coretile, and that these can of
course be mounted on top of each other in all permutations, we
create:
- arm-realview-eb-11mp.dts: the most common variant supported by
QEMU with the pre-revision D baseboard and the revision C core
tile.
- arm-realview-eb-11mp-bbrevd.dts: the revision D baseboard
with the common revision C core tile.
- arm-realview-eb-11mp-ctrevb.dts: the pre-revision D baseboard
with the revision B core tile.
- arm-realview-eb-11mp-bbrevd-ctrevb.dts: the revision D baseboard
with the revision B core time.
Or as a table:
| Core tile: C | Core tile: B
-----------+----------------------------+-----------------------------------
Baseboard: | |

The RealView EB baseboard revision D is a special case as it appears
to be undocumented in ARM official documents, while the Linux kernel
still contains special code for handling it.
commit be4f3c8691
"Add RealView/EB support for the LAN9118 Ethernet chip"
adds support for the SMSC LAN9118 chip used on the D revision of
the baseboard, but no other traces of hardware deviations for this
variant can be found.
This creates a separate top-level .dts file especially for this
board version, so that it gets registered with the right type
of ethernet controller. The ethernet controller modifications
are then put into a separate .dtsi file so it can be overlaid
on other EB variants using the revision D baseboard.
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
The ethernet version in the earlier RealView EB variants is
LAN91C111 and not LAN9118 according to ARM DUI 0303E
"RealView Emulation Baseboard User Guide" page 3-57.
Make sure that this is used for the base variant of the board.
As the DT bindings for LAN91C111 does not specify any power
supplies, these need to be deleted from the DTS file.

On arm/arm64, we depend on the kvm_unmap_hva* callbacks (via
mmu_notifiers::invalidate_*) to unmap the stage2 pagetables when
the userspace buffer gets unmapped. However, when the Hypervisor
process exits without explicit unmap of the guest buffers, the only
notifier we get is kvm_arch_flush_shadow_all() (via mmu_notifier::release
) which does nothing on arm. Later this causes us to access pages that
were already released [via exit_mmap() -> unmap_vmas()] when we actually
get to unmap the stage2 pagetable [via kvm_arch_destroy_vm() ->
kvm_free_stage2_pgd()]. This triggers crashes with CONFIG_DEBUG_PAGEALLOC,
which unmaps any free'd pages from the linear map.

When modifying Stage-2 page tables, we perform cache maintenance to
account for non-coherent page table walks. However, this is unnecessary,
as page table walks are guaranteed to be coherent in the presence of the
virtualization extensions.
Per ARM DDI 0406C.c, section B1.7 ("The Virtualization Extensions"), the
virtualization extensions mandate the multiprocessing extensions.
Per ARM DDI 0406C.c, section B3.10.1 ("General TLB maintenance
requirements"), as described in the sub-section titled "TLB maintenance
operations and the memory order model", this maintenance is not required
in the presence of the multiprocessing extensions.
Hence, we need not perform this cache maintenance when modifying Stage-2
entries.
This patch removes the logic for performing the redundant maintenance.
To ensure visibility and ordering of updates, a dsb(ishst) that was
otherwise implicit in the maintenance is folded into kvm_set_pmd() and
kvm_set_pte().

vms and vcpus have statistics associated with them which can be viewed
within the debugfs. Currently it is assumed within the vcpu_stat_get() and
vm_stat_get() functions that all of these statistics are represented as
u32s, however the next patch adds some u64 vcpu statistics.
Change all vcpu statistics to u64 and modify vcpu_stat_get() accordingly.
Since vcpu statistics are per vcpu, they will only be updated by a single
vcpu at a time so this shouldn't present a problem on 32-bit machines
which can't atomically increment 64-bit numbers. However vm statistics
could potentially be updated by multiple vcpus from that vm at a time.
To avoid the overhead of atomics make all vm statistics ulong such that
they are 64-bit on 64-bit systems where they can be atomically incremented
and are 32-bit on 32-bit systems which may not be able to atomically
increment 64-bit numbers. Modify vm_stat_get() to expect ulongs.

The L2C-220 (AKA L220) and L2C-310 (AKA PL310) cache controllers feature
a Performance Monitoring Unit (PMU), which can be useful for tuning
and/or debugging. This hardware is always present and the relevant
registers are accessible to non-secure accesses. Thus, no special
firmware interface is necessary.
This patch adds support for the PMU, plugging into the usual perf
infrastructure. The overflow interrupt is not always available (e.g. on
RealView PBX A9 it is not wired up at all), and the hardware counters
saturate, so the driver does not make use of this. Instead, the driver
periodically polls and reset counters as required to avoid losing
events due to saturation.

We're trying hard to detect when the HYP idmap overlaps with the
HYP va, as it makes the teardown of a cpu dangerous. But there is
one case where an overlap is completely safe, which is when the
whole of the kernel is idmap'ed, which is likely to happen on 32bit
when RAM is at 0x8000000 and we're using a 2G/2G VA split.
In that case, we can proceed safely.

Most of the sun8i q8 boards have an SDIO wifi controller, on the

couple of error msg-s in dmesg when proving the sdio bus and

The best way to deal with wifi on this boards really is to simply
let the kernel auto-detect usb or sdio wifi controllers, so we

Merge tag 'omap-for-v4.9/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup
Merge "omap soc updates for v4.9 merge window" from Tony Lindgren:
Two patches from Javier Martinez Canillas <javier@osg.samsung.com>
to update mach-omap1 and mach-oamp2 to use IS_ENABLED macro.
* tag 'omap-for-v4.9/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: use IS_ENABLED() instead of checking for built-in or module
ARM: OMAP1: use IS_ENABLED() instead of checking for built-in or module
booting for v4.8 to allow making mach-omap2 device tree only for
v4.9.
We've had Nokia N900 and omap3 LDP board-*.c files remaining
while other omap3 devices have been device tree only for quite
a while now. Also N900 and LDP have had device tree based booting
working for years now, but few drivers for N900 were still only
working in legacy only mode until recently. With the remaining
issues out of the way, we discussed on the mailing lists that
we're finally OK to remove the remaining board-*.c files.
For the timing of this pull request, I wanted to wait until
v4.8-rc1 is out to make sure the legacy booting still works fine
after the merge window before doing it.
And for v4.8, let's not touch any other platform data in case we
still need to revert for some reason. This makes the revert just a
question of adding back the legacy board-*.c files.
Then if no issues, we can remove the unused remaining platform
data later on for v4.9.

The driver is for a trackpad device so is not needed for booting and
makes more sense to have it as module to reduce the kernel image size.
It was probably enabled as built-in because module autoload was not
working when the I2C device was registered by OF but this got fixed
in commit b7d21058b4 ("Input: atmel_mxt_ts - add maxtouch to I2C
table for module autoload") so it's safe to enable as a module now.

The current implementation only works if the da9xxx devices are added
before their drivers are registered. Only then it can apply the fixes to
both devices. Otherwise, the driver for the first device gets probed
before the fix for the second device can be applied. This is what
fails when using the IP core switcher or when having the i2c master
driver as a module.
So, we need to disable both da9xxx once we detected one of them. We now
use i2c_transfer with hardcoded i2c_messages and device addresses, so we
don't need the da9xxx client devices to be instantiated. Because the
fixup is used on specific boards only, the addresses are not going to
change.

These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:
"Node /memory has a reg or ranges property, but no unit name"
The disassembled DTB are almost the same besides an empty chosen

But these boards don't have a memory node defined, so removing the
skeleton.dtsi inclusion in exynos5440.dtsi will cause a change in
the compiled DTB. Add a dummy memory node so the compiled DTB does
not change if the skeleton.dtsi is removed from exynos5440.dtsi.
Eventually the correct starting addresses and sizes should be used
but I didn't find that information.

The USB OTG mode is not supported by Kestone 2 devices, as result, the
USB devices enumeration and detection will not work properly when
kernel is built with CONFIG_USB_DWC3_DUAL_ROLE=y (default for multi
platform build):
- it's required to load gadget drivers manually to make host mode
work and this confuses current Keystone 2 users
- device mode is not working, because port can't detect and switch to
peripheral/host mode dynamically.
Hence, specify usb mode explicitly in DT: usb0 = "host" for all KS2
devices and usb1 = "peripheral" for K2E.
