With stmfx_pinctrl_gpio_init_valid_mask callback, gpio_valid_mask was used
to initialize gpiochip valid_mask for gpiolib. But gpio_valid_mask was not
yet initialized. gpio_valid_mask required gpio-ranges to be registered,
this is the case after gpiochip_add_data call. But init_valid_mask
callback is also called under gpiochip_add_data. gpio_valid_mask
initialization cannot be moved before gpiochip_add_data because
gpio-ranges are not registered.
So, it is not possible to use init_valid_mask callback.
To avoid this issue, get rid of valid_mask and rely on ranges.
Fixes: da9b142ab2c5 ("pinctrl: stmfx: Use the callback to populate valid_mask")

git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into fixes
intel-pinctrl fixes for v5.4 part 2
A couple more fixes for Intel pinctrl drivers:
- Try to avoid glitches when pin is in GPIO mode
- Fix cherryview irq_valid_mask calculation
- Allocate cherryview IRQ chip dynamically to avoid triggering warning
from GPIO core

Keeping the IRQ chip definition static shares it with multiple instances
of the GPIO chip in the system. This is bad and now we get this warning
from GPIO library:
"detected irqchip that is shared with multiple gpiochips: please fix the driver."
Hence, move the IRQ chip definition from being driver static into the struct
intel_pinctrl. So a unique IRQ chip is used for each GPIO chip instance.
This patch is heavily based on the attachment to the bug by Christoph Marz.

Commit 03c4749dd6c7 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux
GPIO translation") has made the cherryview gpio numbers sparse, to get
a 1:1 mapping between ACPI pin numbers and gpio numbers in Linux.
This has greatly simplified things, but the code setting the
irq_valid_mask was not updated for this, so the valid mask is still in
the old "compressed" numbering with the gaps in the pin numbers skipped,
which is wrong as irq_valid_mask needs to be expressed in gpio numbers.
This results in the following error on devices using pin 24 (0x0018) on
the north GPIO controller as an ACPI event source:
[ 0.422452] cherryview-pinctrl INT33FF:01: Failed to translate GPIO to IRQ
This has been reported (by email) to be happening on a Caterpillar CAT T20
tablet and I've reproduced this myself on a Medion Akoya e2215t 2-in-1.
This commit uses the pin number instead of the compressed index into
community->pins to clear the correct bits in irq_valid_mask for GPIOs
using GPEs for interrupts, fixing these errors and in case of the
Medion Akoya e2215t also fixing the LID switch not working.

When consumer requests a pin, in order to be on the safest side,
we switch it first to GPIO mode followed by immediate transition
to the input state. Due to posted writes it's luckily to be a single
I/O transaction.
However, if firmware or boot loader already configures the pin
to the GPIO mode, user expects no glitches for the requested pin.
We may check if the pin is pre-configured and leave it as is
till the actual consumer toggles its state to avoid glitches.

Signal descriptors can represent multi-bit bitfields and so have
explicit "enable" and "disable" states. However many descriptor
instances only describe a single bit, and so the SIG_DESC_SET() macro is
provides an abstraction for the single-bit cases: Its expansion
configures the "enable" state to set the bit and "disable" to clear.
SIG_DESC_CLEAR() was introduced to provide a similar single-bit
abstraction for for descriptors to clear the bit of interest. However
its behaviour was defined as the literal inverse of SIG_DESC_SET() - the
impact is the bit of interest is set in the disable path. This behaviour
isn't intuitive and doesn't align with how we want to use the macro in
practice, so make it clear the bit for both the enable and disable
paths.

intel-pinctrl fixes for v5.4

e3f72b749da2 pinctrl: cherryview: fix Strago DMI workaround
86c5dd6860a6 pinctrl: cherryview: limit Strago DMI workarounds to version 1.0
because even with 1.1 versions of BIOS there are some pins that are
configured as interrupts but not claimed by any driver, and they
sometimes fire up and result in interrupt storms that cause touchpad
stop functioning and other issues.
Given that we are unlikely to qualify another firmware version for a
while it is better to keep the workaround active on all Strago boards.

The 37xx configuration registers are only 32 bits long, so
pins 32-35 spill over into the next register. The calculation
for the register address was done, but the bitmask was not, so
any configuration to pin 32 or above resulted in a bitmask that
overflowed and performed no action.
Fix the register / offset calculation to also adjust the offset.

I enabled it in the dts file. During boot it crashed when the

After long search in the net i found this:

After changing the pin definitions accordingly erverything works.

When multiple instance of iproc-gpio chips are present, a fix up
message[1] is printed during the probe of second and later instances.
This issue is because driver sharing same irq_chip data structure
among multiple instances of driver.
Fix this by allocating irq_chip data structure per instance of
iproc-gpio.
[1] fix up message addressed by this patch
[ 7.862208] gpio gpiochip2: (689d0000.gpio): detected irqchip that
is shared with multiple gpiochips: please fix the driver.

git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into devel
intel-pinctrl for v5.4
A collection of improvements and fixes for Intel pinctrl drivers
including:
- Converting drivers to use new devm_platform_ioremap_resource()
helper function.
- Make Interrupt Status (IS) register configurable.
- Allow locked pins to be requested and used as long as they are not
modified.
- Fix intel_pinctrl_should_save() to translate pin number to GPIO
number where needed. This fixes Asus X571GT touchpad
unresponsiveness issue after suspend/resume cycle.

On Asus X571GT, GPIO 297 is configured as an interrupt and serves
for the touchpad. The touchpad will report input events much less
than expected after S3 suspend/resume, which results in extremely
slow cursor movement. However, the number of interrupts observed
from /proc/interrupts increases much more than expected even no
touching touchpad.
This is due to the value of PADCFG0 of PIN 225 for the interrupt
has been changed from 0x80800102 to 0x80100102. The GPIROUTIOXAPIC
is toggled on which results in the spurious interrupts. The PADCFG0
of PIN 225 is expected to be saved during suspend, but the 297 is
saved instead because the gpiochip_line_is_irq() expect the GPIO
offset but what's really passed to it is PIN number. In this case,
the /sys/kernel/debug/pinctrl/INT3450:00/gpio-ranges shows
288: INT3450:00 GPIOS [436 - 459] PINS [216 - 239]
So gpiochip_line_is_irq() returns true for GPIO offset 297, the
suspend routine spuriously saves the content for PIN 297 which
we expect to save for PIN 225.
This commit maps the PIN number to GPIO offset first in the
intel_pinctrl_should_save() to make sure the values for the
specific PINs can be correctly saved and then restored.

Some firmwares would like to protect pads from being modified by OS
and at the same time provide them to OS as a resource. So, the driver
in such circumstances may request pad and may not change its state.
