pinctrl/amd: only handle irq if it is pending and unmasked
The AMD pinctrl driver demultiplexes GPIO interrupts and fires off their
individual handlers.
If one of these GPIO irqs is configured as a level interrupt, and its
downstream handler is a threaded ONESHOT interrupt, the GPIO interrupt
source is masked by handle_level_irq() until the eventual return of the
threaded irq handler. During this time the level GPIO interrupt status
will still report as high until the actual gpio source is cleared - both
in the individual GPIO interrupt status bit (INTERRUPT_STS_OFF) and in
its corresponding "WAKE_INT_STATUS_REG" bit.
Thus, if another GPIO interrupt occurs during this time,
amd_gpio_irq_handler() will see that the (masked-and-not-yet-cleared)
level irq is still pending and incorrectly call its handler again.
To fix this, have amd_gpio_irq_handler() check for both interrupts status
and mask before calling generic_handle_irq().
Note: Is it possible that this bug was the source of the interrupt storm
on Ryzen when using chained interrupts before commit

Existing solution is spread between the driver and machine code. The

This moves everything into pin controller driver allowing later to
remove the cross-subsystem interaction. Also this is a necessary

pinctrl: samsung: Write external wakeup interrupt mask
The pinctrl driver defines an IRQ chip which handles external wakeup
interrupts, therefore from logical point of view, it is the owner of
external interrupt mask. The register controlling the mask belongs to
Power Management Unit address space so it has to be accessed with PMU
syscon regmap handle.
This mask should be written to hardware during system suspend. Till now
ARMv7 machine code was responsible for this which created a dependency
between pin controller driver and arch/arm/mach code.
Try to rework this dependency so the pinctrl driver will write external
wakeup interrupt mask during late suspend.
Impact on ARMv7 designs (S5Pv210 and Exynos)
============================================
This duplicates setting mask with existing machine code
arch/arm/mach-exynos/suspend.c and arch/arm/mach-s5pv210/pm.c but it is
not a problem - the wakeup mask register will be written twice. The
machine code will be cleaned up later.
The difference between implementation here and ARMv7 machine code
(arch/arm/mach-*) is the time of writing the mask:
1. The machine code is writing the mask quite late during system suspend
path, after offlining secondary CPUs and just before doing actual
suspend.
2. The implementation in pinctrl driver uses late suspend ops, therefore it
will write the mask much earlier. Hopefully late enough, after all
drivers will enable or disable their interrupt wakeups
(enable_irq_wake() etc).
Impact on ARMv8 designs (Exynos5433 and Exynos7)
================================================
The Suspend to RAM was not supported and external wakeup interrupt mask
was not written to HW. This change brings us one step closer to
supporting Suspend to RAM.

pinctrl: samsung: Document hidden requirement about one external wakeup
ARMv7 hardware (S5Pv210 and Exynos SoCs) provides only 32 external
interrupts which can wakeup device from deep sleep modes. On S5Pv210
these are gph0-gph3. On all ARMv7 Exynos designs these are gpx0-gpx3.
There is only one 32-bit register for controlling the external wakeup
interrupt mask (masking and unmasking waking capability of these
interrupts).
This lead to implementation in pinctrl driver and machine code which was
using static memory for storing the mask value and not caring about
multiple devices of pin controller... because only one pin controller
device will be handling this.
Since each pin controller node in Device Tree maps onto one device, this
corresponds to hidden assumption in parsing the Device Tree: external
wakeup interrupts can be defined only once. Make this assumption an
explicit requirement.
ARMv8 Exynos5433 and Exynos7 bring additional 32 external wakeup
interrupts (up to 64 total, banks gpa0-gpa3 and gpf1-gpf5) and another
32-bit wide register for controlling them. Existing code does not
support it but anyway these additional interrupts will be belonging to
the same pin controller device/node.

Add support for the drive strength configuration. Usually, this value is

The PIO controller accepts two values for the low drive configuration: 0

keep the default value which is 0. The drive strength is advertised

...it looks like nonsense. For every pin you see listed:
input bias disabled, input bias high impedance, input bias pull down, input bias pull up, ...
That's because pmic_gpio_config_get() isn't complying with the rules
that pinconf_generic_dump_one() expects. Specifically for boolean
parameters (anything with a "struct pin_config_item" where has_arg is
false) the function expects that the function should return its value
not through the "config" parameter but should return "0" if the value
is set and "-EINVAL" if the value isn't set.
Let's fix this.
From a quick sample of other pinctrl drivers, it appears to be
tradition to also return 1 through the config parameter for these
boolean parameters when they exist. I'm not one to knock tradition,
so I'll follow tradition and return 1 in these cases. While I'm at

dt-bindings: pinctrl: qcom: add gpio-ranges, gpio-reserved-ranges
This patch adds the gpio-ranges and gpio-reserved-ranges property
definitions to the binding text files supported by the pinctrl-msm
driver framework.
gpio-ranges:
For DT-based platforms the pinctrl-msm framework currently relies
on the deprecated-for-DT gpiochip_add_pin_range() function to add
the range of GPIOs to be handled by the pin controller. Due to
interactions within gpiolib code, this causes the pinctrl-msm
driver to bail out (-517) during boot when a gpio-hog is declared.
This can be fatal and cause the system to not boot or reset
(for a detailed explanation and call-trace, refer to patch:
"pinctrl: msm: fix gpio-hog related boot issues" in this series).
gpio-reserved-ranges:
The binding has been added as a precaution since the TrustZone
firmware (aka QSEE), which is running as the hypervisor, might
have reserved certain, but undisclosed pins. Hence reading or
writing to the registers for those pins will cause an
XPU violation and this subsequently crashes the kernel.

pinctrl: mcp23s08: debugfs: Do not restore the INTF register
Apart from the usual stuff, the debugfs code is currently also used for
one non-obvious side effect. It attempts to check whether the chip's
registers are still set to an expected value, and if not, re-initializes
them. It seems that the driver has "always" done so.
The code, however, also checks the INTF register which normally
indicates which pins have caused the recent interrupt. That's a volatile
register, and the datasheet says that writes are ignored in there.
When I'm just cat-ing /sys/kernel/debug/gpio with no SPI traffic and no
nosie on the GPIO lines, I'm not getting any warnings. Once I actually
use these GPIOs and cat that file in parallel, I always seem to get a:
mcp23s08 spi1.1: restoring reg 0x07 from 0x0000 to 0xffff (power-loss?)
This might be a sign that I should not leave my unused inputs floating,
but the code should not be checking a volatile register, anyway. Let's
simply skip this last item in the iteration. I was also considering
removing this enitre re-initialization because it's non-obvious, but the
code survived various refactorings already and has sign-offs by people
who know more than I do, so let's leave it as-is. For now :).
