+Alphascale Clock Controller
+
+The ACC (Alphascale Clock Controller) is responsible of choising proper
+clock source, setting deviders and clock gates.
+
+Required properties for the ACC node:
+ - compatible: must be "alphascale,asm9260-clock-controller"
+ - reg: must contain the ACC register base and size
+ - #clock-cells : shall be set to 1.
+
+Simple one-cell clock specifier format is used, where the only cell is used
+as an index of the clock inside the provider.
+It is encouraged to use dt-binding for clock index definitions. SoC specific
+dt-binding should be included to the device tree descriptor. For example
+Alphascale ASM9260:
+#include <dt-bindings/clock/alphascale,asm9260.h>
+
+This binding contains two types of clock providers:
+ _AHB_ - AHB gate;
+ _SYS_ - adjustable clock source. Not all peripheral have _SYS_ clock provider.
+All clock specific details can be found in the SoC documentation.

+DT bindings for Renesas R-Mobile and SH-Mobile memory controllers
+=================================================================
+
+Renesas R-Mobile and SH-Mobile SoCs contain one or more memory controllers.
+These memory controllers differ from one SoC variant to another, and are called
+by different names ("DDR Bus Controller (DBSC)", "DDR3 Bus State Controller
+(DBSC3)", "SDRAM Bus State Controller (SBSC)").
+
+Currently memory controller device nodes are used only to reference PM
+domains, and prevent these PM domains from being powered down, which would
+crash the system.
+
+As there exist no actual drivers for these controllers yet, these bindings
+should be considered EXPERIMENTAL for now.
+
+Required properties:
+ - compatible: Must be one of the following SoC-specific values:
+ - "renesas,dbsc-r8a73a4" (R-Mobile APE6)
+ - "renesas,dbsc3-r8a7740" (R-Mobile A1)
+ - "renesas,sbsc-sh73a0" (SH-Mobile AG5)
+ - reg: Must contain the base address and length of the memory controller's
+ registers.
+
+Optional properties:
+ - interrupts: Must contain a list of interrupt specifiers for memory
+ controller interrupts, if available.
+ - interrupts-names: Must contain a list of interrupt names corresponding to
+ the interrupts in the interrupts property, if available.
+ Valid interrupt names are:
+ - "sec" (secure interrupt)
+ - "temp" (normal (temperature) interrupt)
+ - power-domains: Must contain a reference to the PM domain that the memory
+ controller belongs to, if available.
+
+Example:
+
+ sbsc1: memory-controller@fe400000 {
+ compatible = "renesas,sbsc-sh73a0";
+ reg = <0xfe400000 0x400>;
+ interrupts = <0 35 IRQ_TYPE_LEVEL_HIGH>,
+ <0 36 IRQ_TYPE_LEVEL_HIGH>;
+ interrupt-names = "sec", "temp";
+ power-domains = <&pd_a4bc0>;

+DT bindings for the Renesas R-Mobile System Controller
+
+== System Controller Node ==
+
+The R-Mobile System Controller provides the following functions:
+ - Boot mode management,
+ - Reset generation,
+ - Power management.
+
+Required properties:
+- compatible: Should be "renesas,sysc-<soctype>", "renesas,sysc-rmobile" as
+ fallback.
+ Examples with soctypes are:
+ - "renesas,sysc-r8a7740" (R-Mobile A1)
+ - "renesas,sysc-sh73a0" (SH-Mobile AG5)
+- reg: Two address start and address range blocks for the device:
+ - The first block refers to the normally accessible registers,
+ - the second block refers to the registers protected by the HPB
+ semaphore.
+
+Optional nodes:
+- pm-domains: This node contains a hierarchy of PM domain nodes, which should
+ match the Power Area Hierarchy in the Power Domain Specifications section of
+ the device's datasheet.
+
+
+== PM Domain Nodes ==
+
+Each of the PM domain nodes represents a PM domain, as documented by the
+generic PM domain bindings in
+Documentation/devicetree/bindings/power/power_domain.txt.
+
+The nodes should be named by the real power area names, and thus their names
+should be unique.
+
+Required properties:
+ - #power-domain-cells: Must be 0.
+
+Optional properties:
+- reg: If the PM domain is not always-on, this property must contain the bit
+ index number for the corresponding power area in the various Power
+ Control and Status Registers. The parent's node must contain the
+ following two properties:
+ - #address-cells: Must be 1,
+ - #size-cells: Must be 0.
+ If the PM domain is always-on, this property must be omitted.
+
+
+Example:
+
+This shows a subset of the r8a7740 PM domain hierarchy, containing the
+C5 "always-on" domain, 2 of its subdomains (A4S and A4SU), and the A3SP domain,
+which is a subdomain of A4S.
+
+ sysc: system-controller@e6180000 {
+ compatible = "renesas,sysc-r8a7740", "renesas,sysc-rmobile";
+ reg = <0xe6180000 0x8000>, <0xe6188000 0x8000>;
+
+ pm-domains {
+ pd_c5: c5 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ #power-domain-cells = <0>;
+
+ pd_a4s: a4s@10 {
+ reg = <10>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ #power-domain-cells = <0>;
+
+ pd_a3sp: a3sp@11 {
+ reg = <11>;
+ #power-domain-cells = <0>;
+ };
+ };
+
+ pd_a4su: a4su@20 {
+ reg = <20>;
+ #power-domain-cells = <0>;
+ };
+ };
+ };
+ };
+
+
+== PM Domain Consumers ==
+
+Hardware blocks belonging to a PM domain should contain a "power-domains"
+property that is a phandle pointing to the corresponding PM domain node.
+
+Example:
+
+ tpu: pwm@e6600000 {
+ compatible = "renesas,tpu-r8a7740", "renesas,tpu";
+ reg = <0xe6600000 0x100>;
