5285b5ed04 pinctrl: aw9523: fix can_sleep flag for GPIO chip
The GPIO expander is connected via I2C, thus the can_sleep flag has to
be set to true. This fixes spurious "scheduling while atomic" bugs
in the kernel ringbuffer.

8ff4fb276e pinctrl: amd: Clear GPIO debounce for suspend
soc-button-array hardcodes a debounce value by means of gpio_keys
which uses pinctrl-amd as a backend to program debounce for a GPIO.

This hardcoded value doesn't match what the firmware intended to be
programmed in _AEI. The hardcoded debounce leads to problems waking
from suspend. There isn't appetite to conditionalize the behavior in
soc-button-array or gpio-keys so clear it when the system suspends to
avoid problems with being able to resume.

46147490b4 pinctrl: nuvoton: Fix boot on ma35dx platforms
As part of a wider cleanup trying to get rid of OF specific APIs, an
incorrect (and partially unrelated) cleanup was introduced.

The goal was to replace a device_for_each_chil_node() loop including an
additional condition inside by a macro doing both the loop and the
check on a single line.

The snippet:

	device_for_each_child_node(dev, child)
		if (fwnode_property_present(child, "gpio-controller"))
			continue;

was replaced by:

	for_each_gpiochip_node(dev, child)

which expands into:

	device_for_each_child_node(dev, child)
		for_each_if(fwnode_property_present(child, "gpio-controller"))

This change is actually doing the opposite of what was initially
expected, breaking the probe of this driver, breaking at the same time
the whole boot of Nuvoton platforms (no more console, the kernel WARN()).

Revert these two changes to roll back to the correct behavior.

93712205ce pinctrl: qcom: msm: mark certain pins as invalid for interrupts
On some platforms, the UFS-reset pin has no interrupt logic in TLMM but
is nevertheless registered as a GPIO in the kernel. This enables the
user-space to trigger a BUG() in the pinctrl-msm driver by running, for
example: `gpiomon -c 0 113` on RB2.

The exact culprit is requesting pins whose intr_detection_width setting
is not 1 or 2 for interrupts. This hits a BUG() in
msm_gpio_irq_set_type(). Potentially crashing the kernel due to an
invalid request from user-space is not optimal, so let's go through the
pins and mark those that would fail the check as invalid for the irq chip
as we should not even register them as available irqs.

This function can be extended if we determine that there are more
corner-cases like this.

5558f27a58 pinctrl: sunxi: dt: Consider pin base when calculating bank number from pin
In prepare_function_table() when the pinctrl function table IRQ entries
are generated, the pin bank is calculated from the absolute pin number;
however the IRQ bank mux array is indexed from the first pin bank of the
controller. For R_PIO controllers, this means the absolute pin bank is
way off from the relative pin bank used for array indexing.

Correct this by taking into account the pin base of the controller.

08dcbe30be pinctrl: freescale: Add support for imx943 pinctrl
The i.MX943 System Manager (SM) firmware supports the System Control
Management Interface (SCMI) pinctrl protocol, similar to the i.MX95 SM.
The base offset for the i.MX943 IOMUXC Daisy input register differs from
that of the i.MX95. Update the pinctrl-imx-scmi driver to add support for
i.MX943.

1c9977b263 pinctrl: mediatek: eint: Fix invalid pointer dereference for v1 platforms
Commit 3ef9f710ef ("pinctrl: mediatek: Add EINT support for multiple
addresses") introduced an access to the 'soc' field of struct
mtk_pinctrl in mtk_eint_do_init() and for that an include of
pinctrl-mtk-common-v2.h.

However, pinctrl drivers relying on the v1 common driver include
pinctrl-mtk-common.h instead, which provides another definition of
struct mtk_pinctrl that does not contain an 'soc' field.

Since mtk_eint_do_init() can be called both by v1 and v2 drivers, it
will now try to dereference an invalid pointer when called on v1
platforms. This has been observed on Genio 350 EVK (MT8365), which
crashes very early in boot (the kernel trace can only be seen with
earlycon).

In order to fix this, since 'struct mtk_pinctrl' was only needed to get
a 'struct mtk_eint_pin', make 'struct mtk_eint_pin' a parameter
of mtk_eint_do_init() so that callers need to supply it, removing
mtk_eint_do_init()'s dependency on any particular 'struct mtk_pinctrl'.

219182fe21 pinctrl: Switch to irq_domain_create_*()
irq_domain_add_*() interfaces are going away as being obsolete now.
Switch to the preferred irq_domain_create_*() ones. Those differ in the
node parameter: They take more generic struct fwnode_handle instead of
struct device_node. Therefore, of_fwnode_handle() is added around the
original parameter.

Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

After recent changes, pinctrl-amd will not support hibernation when
CONFIG_HIBERNATION is set and CONFIG_SUSPEND isn't because it will not
register amd_gpio_pm_ops then.

Address this by restoring dependencies on CONFIG_PM_SLEEP where
necessary for hibernation support.

b841c1d84a pinctrl: amd: Fix use of undeclared identifier 'pinctrl_amd_s2idle_dev_ops'
`pinctrl_amd_s2idle_dev_ops` is hidden under both `CONFIG_ACPI` and
`CONFIG_PM_SLEEP` so the functions that use it need the same scope.

Adjust checks to look for both, and while updating make it CONFIG_SUSPEND
instead as that's what the ACPI header uses.

5488aa013e pinctrl: renesas: rzg2l: Add support for RZ/V2N SoC
Add pinctrl support for the Renesas RZ/V2N SoC by reusing the existing
RZ/V2H(P) pin configuration data. The PFC block is nearly identical, with
the only difference being the absence of `PCIE1_RSTOUTB` on RZ/V2N.

To handle this, the rzv2h_dedicated_pins array is refactored into a common
and pcie1 subset. This enables reuse of the common portion across both
SoCs, while excluding PCIE1_RSTOUTB for RZ/V2N.

This change allows the pinctrl-rzg2l driver to support RZ/V2N without
duplicating large parts of the RZ/V2H configuration.
