Some systems such as the Microsoft Surface Laptop 4 leave interrupts
enabled and configured for use in sleep states on boot, which cause
unexpected behaviour such as spurious wakes and failed resumes in
s2idle states.
As interrupts should not be enabled until they are claimed and
explicitly enabled, disabling any interrupts mistakenly left enabled by
firmware should be safe.

When resuming from low power, the driver attempts to restore the
configuration of some pins. This is done by a call to:
stm32_pinctrl_restore_gpio_regs(struct stm32_pinctrl *pctl, u32 pin)
where 'pin' must be a valid pin value (i.e. matching some 'groups->pin').
Fix the current implementation which uses some wrong 'pin' value.

This reverts commit a49d784d5a8272d0f63c448fe8dc69e589db006e.
The updated binding was wrong / invalid and has been reverted. There
isn't any upstream kernel DTS using it and Broadcom isn't known to use
it neither. There is close to zero chance this will cause regression for
anyone.
Actually in-kernel bcm5301x.dtsi still uses the old good binding and so
it's broken since the driver update. This revert fixes it.

Pull asm-generic fixes from Arnd Bergmann:
"There is one build fix for Arm platforms that ended up impacting most
architectures because of the way the drivers/firmware Kconfig file is
wired up:
The CONFIG_QCOM_SCM dependency have caused a number of randconfig
regressions over time, and some still remain in v5.15-rc4. The fix we
agreed on in the end is to make this symbol selected by any driver
using it, and then building it even for non-Arm platforms with
CONFIG_COMPILE_TEST.
To make this work on all architectures, the drivers/firmware/Kconfig
file needs to be included for all architectures to make the symbol
itself visible.
In a separate discussion, we found that a sound driver patch that is
pending for v5.16 needs the same change to include this Kconfig file,
so the easiest solution seems to have my Kconfig rework included in
v5.15.
Finally, the branch also includes a small unrelated build fix for
NOMMU architectures"

Now that SCM can be a loadable module, we have to add another
dependency to avoid link failures when ipa or adreno-gpu are
built-in:
aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe':
ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available'
ld.lld: error: undefined symbol: qcom_scm_is_available
>>> referenced by adreno_gpu.c
>>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a
This can happen when CONFIG_ARCH_QCOM is disabled and we don't select
QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd
use a similar dependency here to what we have for QCOM_RPROC_COMMON,
but that causes dependency loops from other things selecting QCOM_SCM.
This appears to be an endless problem, so try something different this
time:
- CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on'
but that is simply selected by all of its users
- All the stubs in include/linux/qcom_scm.h can go away
- arm-smccc.h needs to provide a stub for __arm_smccc_smc() to
allow compile-testing QCOM_SCM on all architectures.
- To avoid a circular dependency chain involving RESET_CONTROLLER
and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement.
According to my testing this still builds fine, and the QCOM
platform selects this symbol already.

The separation of pinctrl and gpio drivers created a tiny window where
a pinconfig setting might produce a null-pointer dereference.
The affected device were rk3288-veyron devices in this case.
Pinctrl-hogs are claimed when the pinctrl driver is registered,
at which point their pinconfig settings will be applied.
At this time the now separate gpio devices will not have been created
yet and the matching driver won't have probed yet, making the gpio->foo()
call run into a null-ptr.
As probing is not really guaranteed to have been completed at a specific
time, introduce a queue that can hold the output settings until the gpio
driver has probed and will (in a separate patch) fetch the elements
of the list.
We expect the gpio driver to empty the list, but will nevertheless empty
it ourself on remove if that didn't happen.

pmic_gpio_child_to_parent_hwirq() and
gpiochip_populate_parent_fwspec_fourcell() translate a pinctrl-
spmi-gpio irqspec to an SPMI controller irqspec. When they do
this, they use a fixed SPMI slave ID of 0 and a fixed GPIO
peripheral offset of 0xC0 (corresponding to SPMI address 0xC000).
This translation results in an incorrect irqspec for secondary
PMICs that don't have a slave ID of 0 as well as for PMIC chips
which have GPIO peripherals located at a base address other than
0xC000.
Correct this issue by passing the slave ID of the pinctrl-spmi-
gpio device's parent in the SPMI controller irqspec and by
calculating the peripheral ID base from the device tree 'reg'
property of the pinctrl-spmi-gpio device.

Intel Keem Bay is a computer vision AI accelerator SoC based on ARM CPU.
Documentation of Keem Bay: Documentation/vpu/vpu-stack-overview.rst.
Pinctrl IP:
----------
The SoC has a customised pinmux controller IP which controls pin
multiplexing and configuration.
Keem Bay pinctrl IP is not based on and have nothing in common with the
existing pinctrl drivers. The registers used are incompatible with the
existing drivers, so it requires a new driver.
Add pinctrl driver to enable pin control support in the Intel Keem Bay SoC.

1.Rename the original "dmicx" ABIs to "dmic-ifx", since these devices
have only one DMIC module which has multiple input interfaces. The
original naming is easy to make users mistakenly think that the
device has multiple dmic modules. Currently, in the mainline, no
other devicetree out there is using the "sfc" ABI, so we should be
able to replace it safely.
2.Rename the original "ssix-ce0" ABIs to "ssix-ce", since the X2000
have only one ce pin. The original naming is easy to make users
mistakenly think that the device has multiple ce pins. Currently,
in the mainline, no other devicetree out there is using the
"ssix-ce0" ABIs, so we should be able to replace it safely.
3.Split the original "sfc" ABI into "sfc-data", "sfc-ce", "sfc-clk"
to increase the flexibility when configuring the pins. Currently,
in the mainline, no other devicetree out there is using the "sfc"
ABI, so we should be able to replace it safely.
4.There is more than one compatible string in the match table, so
renaming "ingenic_xxxx_of_match[]" to "ingenic_xxxx_of_matches"
is more reasonable, and remove the unnecessary commas in
"ingenic_gpio_of_matches[]" to reduce code size as much as possible.

When we are building all the various pinctrl structures for the
Allwinner pinctrl devices, we do some estimation about the maximum
number of distinct function (names) that we will need.
So far we take the number of pins as an upper bound, even though we
can actually have up to four special functions per pin. This wasn't a
problem until now, since we indeed have typically far more pins than
functions, and most pins share common functions.
However the H616 "-r" pin controller has only two pins, but four
functions, so we run over the end of the array when we are looking for
a matching function name in sunxi_pinctrl_add_function - there is no
NULL sentinel left that would terminate the loop:
[ 8.200648] Unable to handle kernel paging request at virtual address fffdff7efbefaff5
[ 8.209179] Mem abort info:
....
[ 8.368456] Call trace:
[ 8.370925] __pi_strcmp+0x90/0xf0
[ 8.374559] sun50i_h616_r_pinctrl_probe+0x1c/0x28
[ 8.379557] platform_probe+0x68/0xd8
Do an actual worst case allocation (4 functions per pin, three common
functions and the sentinel) for the initial array allocation. This is
now heavily overestimating the number of functions in the common case,
but we will reallocate this array later with the actual number of
functions, so it's only temporarily.

Casting a small array of u8 to an unsigned long is *never* OK:
- it does funny thing when the array size is less than that of a long,
as it accesses random places in the stack
- it makes everything even more fun with a BE kernel
Fix this by building the unsigned long used as a bitmap byte by byte,
in a way that works across endianess and has no undefined behaviours.
An extra BUILD_BUG_ON() catches the unlikely case where the array
would be larger than a single unsigned long.

The software mapping for GPIO, which initially comes from Microsoft,
is subject to change by respective Windows and firmware developers.
Due to the above the driver had been written and published way ahead
of the schedule, and thus the numbering schema used in it is outdated.

Commit 1abd18d1a51a ("pinctrl: samsung: Register pinctrl before GPIO")
changes the order of GPIO and pinctrl registration: now pinctrl is
registered before GPIO. That means gpio_chip->ngpio is not set when
samsung_pinctrl_register() called, and one cannot rely on that value
anymore. Use `pin_bank->nr_pins' instead of `pin_bank->gpio_chip.ngpio'
to fix mentioned inconsistency.
