Merge tag 'reset-for-v5.19' of git://git.pengutronix.de/pza/linux into arm/drivers

Reset controller updates for v5.19

Add Meson-S4 SoC reset controller support to reset-meson, AST2600 LPC
reset controller support to reset-simple, and R9A07G054 USBPHY reset
controller support to reset-rzg2l-usbphy-ctrl. Add ACPI _RST support to
device_reset(), simplify the uniphier-glue reset driver using bulk API
and devres and clean up its dt-bindings docs. Convert most dt-bindings
docs from txt to yaml.

-* Amlogic audio memory arbiter controller
-
-The Amlogic Audio ARB is a simple device which enables or
-disables the access of Audio FIFOs to DDR on AXG based SoC.
-
-Required properties:
-- compatible: 'amlogic,meson-axg-audio-arb' or
-	      'amlogic,meson-sm1-audio-arb'
-- reg: physical base address of the controller and length of memory
-       mapped region.
-- clocks: phandle to the fifo peripheral clock provided by the audio
-	  clock controller.
-- #reset-cells: must be 1.
-
-Example on the A113 SoC:
-
-arb: reset-controller@280 {
-	compatible = "amlogic,meson-axg-audio-arb";
-	reg = <0x0 0x280 0x0 0x4>;

Documentation/devicetree/bindings/reset/st,sti-picophyreset.txt

-STMicroelectronics STi family Sysconfig Picophy SoftReset Controller
-=============================================================================
-
-This binding describes a reset controller device that is used to enable and
-disable on-chip PicoPHY USB2 phy(s) using "softreset" control bits found in
-the STi family SoC system configuration registers.
-
-The actual action taken when softreset is asserted is hardware dependent.
-However, when asserted it may not be possible to access the hardware's
-registers and after an assert/deassert sequence the hardware's previous state
-may no longer be valid.
-
-Please refer to Documentation/devicetree/bindings/reset/reset.txt
-for common reset controller binding usage.
-
-Required properties:
-- compatible: Should be "st,stih407-picophyreset"
-- #reset-cells: 1, see below
-
-Example:
-
-	picophyreset: picophyreset-controller {
-		compatible = "st,stih407-picophyreset";
-		#reset-cells = <1>;
-	};
-
-Specifying picophyreset control of devices
-=======================================
-
-Device nodes should specify the reset channel required in their "resets"
-property, containing a phandle to the picophyreset device node and an
-index specifying which channel to use, as described in
-Documentation/devicetree/bindings/reset/reset.txt.
-
-Example:
-
-	usb2_picophy0: usbpicophy@0 {
-		resets = <&picophyreset STIH407_PICOPHY0_RESET>;
-	};
-
-Macro definitions for the supported reset channels can be found in:
-include/dt-bindings/reset/stih407-resets.h

Documentation/devicetree/bindings/reset/st,sti-powerdown.txt

-STMicroelectronics STi family Sysconfig Peripheral Powerdown Reset Controller
-=============================================================================
-
-This binding describes a reset controller device that is used to enable and
-disable on-chip peripheral controllers such as USB and SATA, using
-"powerdown" control bits found in the STi family SoC system configuration
-registers. These have been grouped together into a single reset controller
-device for convenience.
-
-The actual action taken when powerdown is asserted is hardware dependent.
-However, when asserted it may not be possible to access the hardware's
-registers and after an assert/deassert sequence the hardware's previous state
-may no longer be valid.
-
-Please refer to reset.txt in this directory for common reset
-controller binding usage.
-
-Required properties:
-- compatible: Should be "st,stih407-powerdown"
-- #reset-cells: 1, see below
-
-example:
-
-	powerdown: powerdown-controller {
