Merge tag 'gpio-updates-for-v6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver (Apple SMC) and extensions to existing drivers
for supporting new HW models. A lot of different impovements across
drivers and in core GPIO code. Details on that are in the signed tag
as usual.

We managed to remove some of the legacy APIs. Arnd Bergmann started to
work on making the legacy bits optional so that we may compile them
only for older platforms that still really need them.

Rob Herring has done a lot of work to convert legacy .txt dt-bindings
for GPIO controllers to YAML. There are only a few left now in the
GPIO tree.

A big part of the commits in this PR concern the conversion of GPIO
drivers to using the new line value setter callbacks. This conversion
is now complete treewide (unless I've missed something) and once all
the changes from different trees land in mainline, I'll send you
another PR containing a commit dropping the legacy callbacks from the
tree.

As the quest to pay back technical dept never really ends, we're
starting another set of interface conversions, this time it's about
moving fields specific to only a handful of drivers using the
gpio-mmio helper out of the core gpio_chip structure that every
controller implements and uses. This cycle we introduce a new set of
APIs and convert a few drivers under drivers/gpio/, next cycle we'll
convert remaining modules treewide (in gpio, pinctrl and mfd trees)
and finally remove the old interfaces and move the gpio-mmio fields
into their own structure wrapping gpio_chip.

One last change I should mention here is the rework of the sysfs
interface. In 2016, we introduced the GPIO character device as the
preferred alternative to the sysfs class under /sys/class/gpio. While
it has seen a wide adoption with the help of its user-space
counterpart - libgpiod - there are still users who prefer the
simplicity of sysfs.

As far as the GPIO subsystem is concerned, the problem is not the
existince of the GPIO class as such but rather the fact that it
exposes the global GPIO numbers to the user-space, stopping us from
ever being able to remove the numberspace from the kernel. To that
end, this release we introduced a parallel, limited sysfs interface
that doesn't expose these numbers and only implements a subset of
features that are relevant to the existing users. This is a result of
several discussions over the course of last year and should allow us
to remove the legacy part some time in the future.

Summary:

GPIOLIB core:
- introduce a parallel, limited sysfs user ABI that doesn't expose
the global GPIO numbers to user-space while maintaining backward
compatibility with the end goal of it completely replacing the
existing interface, allowing us to remove it
- remove the legacy devm_gpio_request() routine which has no more
users
- start the process of allowing to compile-out the legacy parts of
the GPIO core for users who don't need it by introducing a new
Kconfig option: GPIOLIB_LEGACY
- don't use global GPIO numbers in debugfs output from the core code
(drivers still do it, the work is ongoing)
- start the process of moving the fields specific to the gpio-mmio
helper out of the core struct gpio_chip into their own structure
that wraps it: create a new header with modern interfaces and
convert several drivers to using it
- remove the platform data structure associated with the gpio-mmio
helper from the kernel after having converted all remaining users
to generic device properties
- remove legacy struct gpio definition as it has no more users

New drivers:
- add the GPIO driver for the Apple System Management Controller

Driver improvements:
- add support for new models to gpio-adp5585, gpio-tps65219 and
gpio-pca953x
- extend the interrupt support in gpio-loongson-64bit
- allow to mark the simulated GPIO lines as invalid in gpio-sim
- convert all remaining GPIO drivers to using the new GPIO value
setter callbacks
- convert gpio-rcar to using simple device power management ops
callbacks
- don't check if current direction of a line is output before setting
the value in gpio-pisosr and ti-fpc202: the GPIO core already
handles that
- also drop unneeded GPIO range checks in drivers, the core already
makes sure we're within bounds when calling driver callbacks
- use dev_fwnode() where applicable across GPIO drivers
- set line value in gpio-zynqmp-modepin and gpio-twl6040 when the
user wants to change direction of the pin to output even though
these drivers don't need to do anything else to actually set the
direction, otherwise a call like gpiod_direction_output(d, 1) will
not result in the line driver high
- remove the reduntant call to pm_runtime_mark_last_busy() from
gpio-arizona
- use lock guards in gpio-cadence and gpio-mxc
- check the return values of regmap functions in gpio-wcd934x and
gpio-tps65912
- use better regmap interfaces in gpio-wcove and gpio-pca953x
- remove dummy GPIO chip callbacks from several drivers in cases
where the GPIO core can already handle their absence
- allow building gpio-palmas as a module

Fixes:
- use correct bit widths (according to the documentation) in
gpio-virtio

Device-tree bindings:
- convert several of the legacy .txt documents for many different
devices to YAML, improving automatic validation
- create a "trivial" GPIO DT schema that covers a wide range of
simple hardware that share a set of basic GPIO properties
- document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
- document a new model for pca95xx
- add and/or remove properties in YAML documents for gpio-rockchip,
fsl,qoriq-gpio, arm,pl061 and gpio-xilinx

Misc:
- some minor refactoring in several places, adding/removing forward
declarations, moving defines to better places, constify the
arguments in some functions, remove duplicate includes, etc.
- documentation updates"

mfd: adp5585: Add support for input devices

The ADP558x family supports a built in keypad matrix decoder which can
be added as an Input device. In order to both support the Input and the
GPIO device, we need to create a bitmap of the supported pins and track
their usage since they can either be used as GPIOs (GPIs) or as part of
the keymap.

We also need to mark special pins busy in case some features are being
used (ex: pwm or reset events).

On top of that adp5585_fill_regmap_config() is renamed and reworked so
that the current struct adp5585_info act as template (they indeed
contain all the different data between variants) which can then be
complemented depending on the device (as identified by the id register).
This is done like this since a lot of the data is pretty much the same
between variants of the same device.

mfd: adp5585: Refactor how regmap defaults are handled

The only thing changing between variants is the regmap default
registers. Hence, instead of having a regmap configuration for every
variant (duplicating lots of fields), add a chip info type of structure
with a regmap ID to identify which defaults to use and populate
regmap_config at runtime given a template plus the id. Also note that
between variants, the defaults can be the same which means the chip info
structure can be used in more than one compatible.

This will also make it simpler adding new chips with more variants.

Also note that the chip info structures are deliberately not const as
they will also contain lots of members that are the same between the
different devices variants and so we will fill those at runtime.
