commit d5301c90716a8e20bc961a348182daca00c8e8f0 upstream.
First argument of acpi_*_address_space_handler() APIs is acpi_handle of
the device, which is incorrectly passed in driver ->remove() path here.
Fix it by passing the appropriate argument and while at it, make both
API calls consistent using ACPI_HANDLE().

[ Upstream commit 635a750d958e158e17af0f524bedc484b27fbb93 ]
On ASUS TUF A16 it is reported that the ITE5570 ACPI device connected to
GPIO 7 is causing an interrupt storm. This issue doesn't happen on
Windows.
Comparing the GPIO register configuration between Windows and Linux
bit 20 has been configured as a pull up on Windows, but not on Linux.
Checking GPIO declaration from the firmware it is clear it *should* have
been a pull up on Linux as well.
```
GpioInt (Level, ActiveLow, Exclusive, PullUp, 0x0000,
"\\_SB.GPIO", 0x00, ResourceConsumer, ,)
{ // Pin list
0x0007
}
```
On Linux amd_gpio_set_config() is currently only used for programming
the debounce. Actually the GPIO core calls it with all the arguments
that are supported by a GPIO, pinctrl-amd just responds `-ENOTSUPP`.
To solve this issue expand amd_gpio_set_config() to support the other
arguments amd_pinconf_set() supports, namely `PIN_CONFIG_BIAS_PULL_DOWN`,
`PIN_CONFIG_BIAS_PULL_UP`, and `PIN_CONFIG_DRIVE_STRENGTH`.

commit 968ab9261627fa305307e3935ca1a32fcddd36cb upstream.
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.
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.

commit 4e5a04be88fe ("pinctrl: amd: disable and mask interrupts on probe").
On some systems, during suspend/resume cycle firmware leaves
an interrupt enabled on a pin that is not used by the kernel.
This confuses the AMD pinctrl driver and causes spurious interrupts.
The driver already has logic to detect if a pin is used by the kernel.
Leverage it to re-initialize interrupt fields of a pin only if it's not

The firmware on some systems may configure GPIO pins to be
an interrupt source in so called "direct IRQ" mode. In such
cases the GPIO controller driver has no idea if those pins
are being used or not. At the same time, there is a known bug
in the firmwares that don't restore the pin settings correctly
after suspend, i.e. by an unknown reason the Rx value becomes
inverted.
Hence, let's save and restore the pins that are configured
as GPIOs in the input mode with GPIROUTIOXAPIC bit set.

commit b8c824a869f220c6b46df724f85794349bafbf23 upstream.
Saving/restoring interrupt and wake status bits across suspend can
cause the suspend to fail if an IRQ is serviced across the
suspend cycle.

[ Upstream commit c551bd81d198bf1dcd4398d5454acdc0309dbe77 ]
In some cases we may get a platform device that has ACPI companion
which is different to the pin control described in the ACPI tables.
This is primarily happens when device is instantiated by board file.
In order to allow this device being enumerated, refactor
intel_pinctrl_get_soc_data() to check the matching data instead of
ACPI companion.

commit fc153c8f283bf5925615195fc9d4056414d7b168 upstream.
H6 requires I/O bias configuration on both of its PIO devices.
Previously it was only done for the main PIO.
The setting for Port L is at bit 0, so the bank calculation needs to
account for the pin base. Otherwise the wrong bit is used.

GPIO 31, 32 can be muxed to GCC_CAMSS_GP(1,2)_CLK respectively but the
function was never assigned to the pingroup (even though the function
exists already).
Add this mode to the related pins.

commit a1d4ef1adf8bbd302067534ead671a94759687ed upstream.
To act as an interrupt controller, a gpio bank relies on the
"interrupt-parent" of the pin controller.
When this optional "interrupt-parent" misses, do not create any IRQ domain.
This fixes a "NULL pointer in stm32_gpio_domain_alloc()" kernel crash when
the interrupt-parent = <exti> property is not declared in the Device Tree.

Some Allwinner SoCs have 2 pinctrls (PIO and R_PIO).
Previous implementation used absolute pin numbering and it was incorrect
for R_PIO pinctrl.
It's necessary to take into account the base pin number.
