DT bindings clean-up from Krzysztof. Each which could give rise to
conflicts, but I haven't seen any.
The YAML conversions happening around the device tree is the biggest

autovalidate these trees against strict schemas and it is paying off
in lots of bugs found and ever prettier device trees. Sooner or later
the transition will be complete, Krzysztof is fixing up all of the

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.

Since commit 502df79b86 ("gpiolib: Warn on drivers still using
static gpiobase allocation") in gpio/for-next, one or more warnings are
printed during boot on systems where the pin controller also provides
GPIO functionality:
gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.
Fix this for ARM-based SH/R-Mobile SoCs by:
1. Taking into account a non-zero GPIO base in the various GPIO chip
callbacks,
2. Switching to dynamic allocation of the GPIO base when support for
legacy function GPIOs is not enabled.
On SuperH SoCs using legacy function GPIOs, the GPIO bases of the GPIO
controller and the GPIO function controller must not be changed, as all
board files rely on the fixed GPIO_* and GPIO_FN_* definitions provided
by the various <cpu/sh*.h> header files.

The External Interrupt Controller (EINTC) on all of the supported
MediaTek SoCs does support input debouncing, but not all of them
index the debounce time values (DBNC_SETTING registers) the same way.
Before this change, in some cases, as an example, requesting a debounce
time of 16 milliseconds would mistakenly set the relative DBNC_SETTING
register to 0x2, resulting in a way shorter debounce time of 500uS.
To fix the aforementioned issue, define three different debounce_time
arrays, reflecting the correct register index for each value and for
each register index variant, and make sure that each SoC pinctrl
driver uses the right one.

Tegra194 has two separate instances of the pin controller, one called
AON (in the always-on domain) and another called "main". Instead of
treating them as a single pin controller, split them up into two
separate controllers. Doing so allows the mapping between the pinmux
and GPIO controllers to be trivial identity mappings and more cleanly
separates the AON from the main IP blocks.

In pinctrl-paris we're calling the .bias_set_combo() callback when we
are asked to set the pin bias to either pull up/down or pull disable.
On newer platforms, this callback is mtk_pinconf_bias_set_combo(),
located in pinctrl-mtk-common-v2.c: this will check the "pull type"
assigned to the requested pin and in case said pin's pull type is
MTK_PULL_PU_PD_RSEL_TYPE, this function will set RSEL first, PUPD
last, which is fine.
The issue comes when we're requesting PIN_CONFIG_BIAS_DISABLE, as
this does *not* require setting RSEL but only PU_PD: in this case,
the arg is MTK_DISABLE (zero), which is not a supported RSEL, due
to which function mtk_pinconf_bias_set_rsel() returns a failure;
because of that, mtk_pinconf_bias_set_pu_pd() is never called,
hence the pin bias is never set to DISABLE.
To fix this issue, add a check to mtk_pinconf_bias_set_rsel(): if
we are entering that function with no pullup requested and at the
same time the arg is MTK_DISABLE, this means that we're trying to
disable pin bias, hence it's safe to return cleanly without ever
setting any RSEL register.
This makes mtk_pinconf_bias_set_combo() happy, going on with setting
the PU_PD registers, which is the only action to actually take to
disable bias on a pin/pingroup.

The mux routes are incomplete for the PX30. This was discovered because
we had a HW design using cif-clkoutm1 with the correct pinmux in the
Device Tree but the clock would still not work.
There are actually two muxing required: the pin muxing (performed by the
usual Device Tree pinctrl nodes) and the "function" muxing (m0 vs m1;
performed by the mux routing inside the driver). The pin muxing was
correct but the function muxing was not.
This adds the missing pins and their configuration for the mux routes
that are already specified in the driver.
Note that there are some "conflicts": it is possible *in Device Tree* to
(attempt to) mux the pins for e.g. clkoutm1 and clkinm0 at the same time
but this is actually not possible in hardware (because both share the
same bit for the function muxing). Since it is an impossible hardware
design, it is not deemed necessary to prevent the user from attempting
to "misconfigure" the pins/functions.

Merge tag 'intel-pinctrl-v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into devel
intel-pinctrl for v6.1-2
* Add missing and remove unused headers in the pin control and GPIO drivers
* Revise the pin control and GPIO headers
There is a few things done:
- include only the headers we are direct user of
- when pointer is in use, provide a forward declaration
- add missing headers
- group generic headers and subsystem headers
- sort each group alphabetically
While at it, fix some awkward indentations.

Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.
