The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

The driver called pwm_config() and pwm_enable() separately. Today both
are wrappers for pwm_apply_might_sleep() and it's more effective to call
this function directly and only once. Also don't configure the
duty_cycle and period if the next operation is to disable the PWM so
configure the PWM in max77693_haptic_enable().

With the direct use of pwm_apply_might_sleep() the need to call
pwm_apply_args() in .probe() is now gone, too, so drop this one.

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

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

     direction, otherwise a call like gpiod_direction_output(d, 1) will

Use touch-overlay to support overlay objects such as buttons and a
resized frame defined in the device tree.

A key event will be generated if the coordinates of a touch event are
within the area defined by the button properties.

Some touch devices provide mechanical overlays with different objects
like buttons or clipped touchscreen surfaces.

In order to support these objects, add a series of helper functions
to the input subsystem to transform them into overlay objects via
device tree nodes.

These overlay objects consume the raw touch events and report the
expected input events depending on the object properties.

Note that the current implementation allows for multiple definitions
of touchscreen areas (regions that report touch events), but only the
first one will be used for the touchscreen device that the consumers
typically provide.
Should the need for multiple touchscreen areas arise, additional
touchscreen devices would be required at the consumer side.
There is no limitation in the number of touch areas defined as buttons.

<title>Input: atkbd - correctly map F13 - F24</title>

Currently only F23 is correctly mapped for PS/2 keyboards.

According to this table:
https://download.microsoft.com/download/1/6/1/161ba512-40e2-4cc9-843a-923143f3456c/translate.pdf

- F24 and Zenkaku/Hankaku share the same scancode, but since in real world
Zenkaku/Hankaku keys seem to just use the tilde scancode, this patch binds the
scancode to F24. Note that on userspace side the KEY_ZENKAKUHANKAKU keycode is
currently not bound in xkeyboard-config, so it is (mostly*) unused anyway.

* Qt on Wayland and therefore KDE on Wayland can see the keypress anyway for
some reason and it is actually used in a touchpad toggle shortcut, but this is
currently being fixed in both KDE and xkeyboard-config to make this less weird,
so it could directly be fixed to correctly handle the F24 keypress instead.

- The scancodes for F13-F22 are currently unmapped so there will probably be no
harm in mapping them. This would also fix the issue that some of these keys
can't be mapped as the target from userspace using the `setkeycodes` command.
