This GPIO controller can serve as an interrupt controller as well on the
GPIOs it handles.
An interrupt is generated whenever a GPIO line changes and the
interrupt for this GPIO line is enabled. This means that both the
changes from low to high and high to low generate an interrupt.
For some use cases, it makes sense to ignore the high to low change and
not generate an interrupt. Such a use case is a line that is hold in a
level high/low manner until the event holding the line gets acked.
This can be achieved by making sure the interrupt on the GPIO controller
side gets acked and masked only after the line gets hold in its default
state, this is what's done with the fasteoi functions.
Only IRQ_TYPE_EDGE_BOTH and IRQ_TYPE_LEVEL_HIGH are supported for now.

These codecs have a variable number of I/O lines each of which
is individually selectable to a wide range of possible functions.
The functionality is slightly different from the traditional muxed
GPIO since most of the functions can be mapped to any pin (and even
the same function to multiple pins). Most pins have a dedicated
"alternate" function that is only available on that pin. The
alternate functions are usually a group of signals, though it is
not always necessary to enable the full group, depending on the
alternate function and how it is to be used. The mapping between
alternate functions and GPIO pins varies between codecs depending
on the number of alternate functions and available pins.

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.15 kernel cycle:
Core:
- The pin control Kconfig entry PINCTRL is now turned into a
menuconfig option. This obviously has the implication of making the
subsystem menu visible in menuconfig. This is happening because of
two things:
(a) Intel have started to deploy and depend on pin controllers in
a way that is affecting users directly. This happens on the
highly integrated laptop chipsets named after geographical
places: baytrail, broxton, cannonlake, cedarfork, cherryview,
denverton, geminilake, lewisburg, merrifield, sunrisepoint...
It started a while back and now it is ever more evident that
this is crucial infrastructure for x86 laptops and not an
embedded obscurity anymore. Users need to be aware.
(b) Pin control expanders on I2C and SPI that are arch-agnostic.
Currently Semtech SX150X and Microchip MCP28x08 but more are
expected. Users will have to be able to configure these in
directly for their set-up.
- Just go and select GPIOLIB now that we made sure that GPIOLIB is a
very vanilla subsystem. Do not depend on it, if we need it, select
it.
- Exposing the pin control subsystem in menuconfig uncovered a bunch
of obscure bugs that are now hopefully fixed, all more or less
pertaining to Blackfin.
- Unified namespace for cross-calls between pin control and GPIO.
- New support for clock skew/delay generic DT bindings and generic
pin config options for this.
- Minor documentation improvements.
Various:
- The Renesas SH-PFC pin controller has evolved a lot. It seems
Renesas are churning out new SoCs by the minute.
- A bunch of non-critical fixes for the Rockchip driver.
- Improve the use of library functions instead of open coding.
- Support the MCP28018 variant in the MCP28x08 driver.
- Static constifying"

if (readl(®s->invert_set) & pintbit)
^~
It seems the driver need to include <asm/gpio.h> and <asm/irq.h>
to compile.
The Blackfin architecture was re-defining the Kconfig
PINCTRL symbol which is not OK, so replaced this with
PINCTRL_BLACKFIN_ADI2 which selects PINCTRL and PINCTRL_ADI2
just like most arches do.
Further, the old GPIO driver symbol GPIO_ADI was possible to
select at the same time as selecting PINCTRL. This was not
working because the arch-local <asm/gpio.h> header contains
an explicit #ifndef PINCTRL clause making compilation break
if you combine them. The same is true for DEBUG_MMRS.
Make sure the ADI2 pinctrl driver is not selected at the same
time as the old GPIO implementation. (This should be converted
to use gpiolib or pincontrol and move to drivers/...) Also make
sure the old GPIO_ADI driver or DEBUG_MMRS is not selected at
the same time as the new PINCTRL implementation, and only make
PINCTRL_ADI2 selectable for the Blackfin families that actually
have it.
This way it is still possible to add e.g. I2C-based pin
control expanders on the Blackfin.

When meson pinctrl is enabled, all meson platforms pinctrl drivers are
built in the kernel, with a significant amount of data.
This leads to situation where pinctrl drivers targeting an architecture
are also compiled and shipped on another one (ex: meson8 - ARM - compiled
and shipped on ARM64 builds). This is a waste of memory we can easily
avoid.
This change makes 4 pinctrl drivers (1 per SoC) out the original single
driver, allowing to compile and ship only the ones required.

RK805 is one of Rockchip PMICs family, it has 2 output only GPIOs.
This driver is also designed for other Rockchip PMICs to expend.
Different PMIC maybe have different pin features, for example,
RK816 has one pin which can be used for TS or GPIO(input/out).
The mainly difference between PMICs pins are pinmux, direction
and output value, that is 'struct rk805_pin_config'.
