commit 4e5a04be88fe ("pinctrl: amd: disable and mask interrupts on probe")
was well intentioned to mask a firmware issue on a surface laptop, but it
has a few problems:
1. It had a bug in the loop handling for iteration 63 that lead to other
problems with GPIO0 handling.
2. It disables interrupts that are used internally by the SOC but masked
by default.
3. It masked a real firmware problem in some chromebooks that should have
been caught during development but wasn't.
There has been a lot of other development around s2idle; particularly
around handling of the spurious wakeups. If there is still a problem on
the original reported surface laptop it should be avoided by adding a quirk
to gpiolib-acpi for that system instead.

Leverage gpiochip_line_is_irq to check whether a pin has an irq
associated with it. The previous check ("irq == 0") didn't make much
sense. The irq variable refers to the pinctrl irq, and has nothing do to
with an individual pin.
On some systems, during suspend/resume cycle, the firmware leaves
an interrupt enabled on a pin that is not used by the kernel.
Without this patch that caused an interrupt storm.

commit 4e5a04be88fe ("pinctrl: amd: disable and mask interrupts on probe")
had a mistake in loop iteration 63 that it would clear offset 0xFC instead
of 0x100. Offset 0xFC is actually `WAKE_INT_MASTER_REG`. This was
clearing bits 13 and 15 from the register which significantly changed the
expected handling for some platforms for GPIO0.

had a mistake in loop iteration 63 that it would clear offset 0xFC instead
of 0x100. Offset 0xFC is actually `WAKE_INT_MASTER_REG`. This was
clearing bits 13 and 15 from the register which significantly changed the
expected handling for some platforms for GPIO0.
commit b26cd9325be4 ("pinctrl: amd: Disable and mask interrupts on resume")
actually fixed this bug, but lead to regressions on Lenovo Z13 and some
other systems. This is because there was no handling in the driver for bit
15 debounce behavior.
Quoting a public BKDG:
```
EnWinBlueBtn. Read-write. Reset: 0. 0=GPIO0 detect debounced power button;
Power button override is 4 seconds. 1=GPIO0 detect debounced power button
in S3/S5/S0i3, and detect "pressed less than 2 seconds" and "pressed 2~10
seconds" in S0; Power button override is 10 seconds
```
Cross referencing the same master register in Windows it's obvious that
Windows doesn't use debounce values in this configuration. So align the
Linux driver to do this as well. This fixes wake on lid when
WAKE_INT_MASTER_REG is properly programmed.

Pull pin control updates from Linus Walleij:
"Mostly drivers! Nothing special: some new Qualcomm chips as usual, and
the new NXP S32 and nVidia BlueField-3.
Core changes:
- Make a lot of pin controllers with GPIO and irqchips immutable,
i.e. not living structs, but const structs. This is driving a
changed initiated by the irqchip maintainers.
New drivers:
- New driver for the NXP S32 SoC pin controller
- As part of a thorough cleanup and restructuring of the
Ralink/Mediatek drivers, the Ralink MIPS pin control drivers were
folded into the Mediatek directory and the family is renamed
"mtmips". The Ralink chips live on as Mediatek MIPS family where
new variants can be added. As part of this work also the device
tree bindings were reworked.
- New subdriver for the Qualcomm SM7150 SoC.
- New subdriver for the Qualcomm IPQ9574 SoC.
- New driver for the nVidia BlueField-3 SoC.
- Support for the Qualcomm PMM8654AU mixed signal circuit GPIO.
- Support for the Qualcomm PMI632 mixed signal circuit GPIO.
Improvements:
- Add some missing pins and generic cleanups on the Renesas r8a779g0
and r8a779g0 pin controllers. Generic Renesas extension for power
source selection on several SoCs.
- Misc cleanups for the Atmel AT91 and AT91-PIO4 pin controllers
- Make the GPIO mode work on the Qualcomm SM8550-lpass-lpi driver.
- Several device tree binding cleanups as the binding YAML syntax is
solidifying"

In the past setting the pin direction called pinctrl_gpio_direction()
which uses a mutex to serialize this. That was changed to set the
direction directly in the pin controller driver, but that lost the
serialization mechanism. Since the direction of multiple pins are in
the same register you can have a race condition, something that was
in fact observed with the cec-gpio driver.
Add a new spinlock to serialize writing to the FSEL registers.

Convert the driver to immutable irq-chip with a bit of
intuition.
I switched to consistently using irqd_to_hwirq() consistently
while we are at it.
As the driver now needs to get the gpio_chip in the .irq_mask
and .irq_unmask callbacks, I switched to a pattern where we
first fetch the gpio_chip and then the state container from
that in two steps. The compiler will do the same thing anyway.

I switched to using irqd_to_hwirq() consistently while we

This driver does not use the GPIOCHIP_IRQ_RESOURCE_HELPERS
as it defines its own resource reservations, simply in
order to turn IRQ lines into inputs on initialization.
Also switched the open coded calls to gpiochip_lock_as_irq()
to gpiochip_reqres_irq() so we also get the right module
reference counting.

As the of_node member of struct device always exists, and there is a
dummy of of_device_get_match_data() for the !CONFIG_OF case, there is no
longer a need to protect code using these interfaces with an #ifdef.

It does not make sense to have a comma after a sentinel, as any new
elements must be added before the sentinel. Hence drop all such commas.
Add comments to clarify the purpose of the empty elements.

Currently, the Renesas pin control driver supports pins that can switch
their I/O voltage levels between either 1.8V and 3.3V, or between 2.5V
and 3.3V. However, some SoCs have pins that can switch between 1.8V and
2.5V.
Add support for this by replacing the separate SH_PFC_PIN_CFG_IO_VOLTAGE
capability and voltage level flags by a 2-bit field, to cover three
possible I/O voltage switching options.

Commit 537db25ca330dce0 ("pinctrl: renesas: Add I/O voltage level
flag") introduced new flags to support pins that can switch their
voltage levels between either 1.8V and 3.3V, or between 2.5V and 3.3V.
The old SH_PFC_PIN_CFG_IO_VOLTAGE flag was retained to avoid having to
change existing drivers.
Replace SH_PFC_PIN_CFG_IO_VOLTAGE by SH_PFC_PIN_CFG_IO_VOLTAGE_18_33, to
make the voltage configuration explicit, and to prepare for the advent
of support for more voltage levels.

The POC Control Register 0 (POCCTRL0) on R-Car D3 is not registered in
the pinmux_ioctrl_regs[] array. Hence it is not saved/restored during
suspend/resume, and its contents may be lost after s2ram.
This went unnoticed when improving suspend/resume support in commit
d92ee9cf8ec8d7fe ("pinctrl: sh-pfc: rcar-gen3: Retain TDSELCTRL register
across suspend/resume").
Fix this by moving the pinmux_ioctrl_regs[] array up, and adding the
POCCTRL0 register.

The comment recently added talking about PIN_CONFIG_INPUT_ENABLE is
clearly missing the word "and". Comments live forever, so let's fix
it.
