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"

-GPIO controllers on MPC8xxx SoCs
-
-This is for the non-QE/CPM/GUTs GPIO controllers as found on
-8349, 8572, 8610 and compatible.
-
-Every GPIO controller node must have #gpio-cells property defined,
-this information will be used to translate gpio-specifiers.
-See bindings/gpio/gpio.txt for details of how to specify GPIO
-information for devices.
-
-The GPIO module usually is connected to the SoC's internal interrupt
-controller, see bindings/interrupt-controller/interrupts.txt (the
-interrupt client nodes section) for details how to specify this GPIO
-module's interrupt.
-
-The GPIO module may serve as another interrupt controller (cascaded to
-the SoC's internal interrupt controller).  See the interrupt controller
-nodes section in bindings/interrupt-controller/interrupts.txt for
-details.
-
-Required properties:
-- compatible:		"fsl,<chip>-gpio" followed by "fsl,mpc8349-gpio"
-			for 83xx, "fsl,mpc8572-gpio" for 85xx, or
-			"fsl,mpc8610-gpio" for 86xx.
-- #gpio-cells:		Should be two. The first cell is the pin number
-			and the second cell is used to specify optional
-			parameters (currently unused).
-- interrupts:		Interrupt mapping for GPIO IRQ.
-- gpio-controller:	Marks the port as GPIO controller.
-
-Optional properties:
-- interrupt-controller:	Empty boolean property which marks the GPIO
-			module as an IRQ controller.
-- #interrupt-cells:	Should be two.  Defines the number of integer
-			cells required to specify an interrupt within
-			this interrupt controller.  The first cell
-			defines the pin number, the second cell
-			defines additional flags (trigger type,
-			trigger polarity).  Note that the available
-			set of trigger conditions supported by the
-			GPIO module depends on the actual SoC.
-
-Example of gpio-controller nodes for a MPC8347 SoC:
-
-	gpio1: gpio-controller@c00 {
-		#gpio-cells = <2>;
-		compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
-		reg = <0xc00 0x100>;

-		reg = <0xd00 0x100>;
-		interrupt-parent = <&ipic>;

-Keystone 2 DSP GPIO controller bindings
-
-HOST OS userland running on ARM can send interrupts to DSP cores using
-the DSP GPIO controller IP. It provides 28 IRQ signals per each DSP core.
-This is one of the component used by the IPC mechanism used on Keystone SOCs.
-
-For example TCI6638K2K SoC has 8 DSP GPIO controllers:
- - 8 for C66x CorePacx CPUs 0-7
-
-Keystone 2 DSP GPIO controller has specific features:
-- each GPIO can be configured only as output pin;
-- setting GPIO value to 1 causes IRQ generation on target DSP core;
-- reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
-  pending.
-
-Required Properties:
-- compatible: should be "ti,keystone-dsp-gpio"
-- ti,syscon-dev: phandle/offset pair. The phandle to syscon used to
-  access device state control registers and the offset of device's specific
-  registers within device state control registers range.
-- gpio-controller: Marks the device node as a gpio controller.
-- #gpio-cells: Should be 2.
-
-Please refer to gpio.txt in this directory for details of the common GPIO
-bindings used by client devices.
-
-Example:
-	dspgpio0: keystone_dsp_gpio@2620240 {
-		compatible = "ti,keystone-dsp-gpio";

-  for general purpose. It is manipulated by the GRF_SOC_CON10 register.
-  If needed in the future support for the HDMI pins can also be added.

+  Keystone 2 DSP GPIO controller has specific features:
+  - each GPIO can be configured only as output pin;
+  - setting GPIO value to 1 causes IRQ generation on target DSP core;
+  - reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
+    pending.
