Merge tag 'dt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC DT updates from Olof Johansson:
 "DT and DT-conversion-related changes for various ARM platforms.  Most
  of these are to enable various devices on various boards, etc, and not
  necessarily worth enumerating.

  New boards and systems continue to come in as new devicetree files
  that don't require corresponding C changes any more, which is
  indicating that the system is starting to work fairly well.

  A few things worth pointing out:

   * ST Ericsson ux500 platforms have made the major push to move over
     to fully support the platform with DT
   * Renesas platforms continue their conversion over from legacy
     platform devices to DT-based for hardware description"

+* Renesas CPG DIV6 Clock
+
+The CPG DIV6 clocks are variable factor clocks provided by the Clock Pulse
+Generator (CPG). They clock input is divided by a configurable factor from 1
+to 64.
+
+Required Properties:
+
+  - compatible: Must be one of the following
+    - "renesas,r8a7790-div6-clock" for R8A7790 (R-Car H2) DIV6 clocks
+    - "renesas,r8a7791-div6-clock" for R8A7791 (R-Car M2) DIV6 clocks
+    - "renesas,cpg-div6-clock" for generic DIV6 clocks
+  - reg: Base address and length of the memory resource used by the DIV6 clock
+  - clocks: Reference to the parent clock
+  - #clock-cells: Must be 0
+  - clock-output-names: The name of the clock as a free-form string
+
+
+Example
+-------
+
+	sd2_clk: sd2_clk@e6150078 {
+		compatible = "renesas,r8a7790-div6-clock", "renesas,cpg-div6-clock";

+* Renesas CPG Module Stop (MSTP) Clocks
+
+The CPG can gate SoC device clocks. The gates are organized in groups of up to
+32 gates.
+
+This device tree binding describes a single 32 gate clocks group per node.
+Clocks are referenced by user nodes by the MSTP node phandle and the clock
+index in the group, from 0 to 31.
+
+Required Properties:
+
+  - compatible: Must be one of the following
+    - "renesas,r8a7790-mstp-clocks" for R8A7790 (R-Car H2) MSTP gate clocks
+    - "renesas,r8a7791-mstp-clocks" for R8A7791 (R-Car M2) MSTP gate clocks
+    - "renesas,cpg-mstp-clock" for generic MSTP gate clocks
+  - reg: Base address and length of the I/O mapped registers used by the MSTP
+    clocks. The first register is the clock control register and is mandatory.
+    The second register is the clock status register and is optional when not
+    implemented in hardware.
+  - clocks: Reference to the parent clocks, one per output clock. The parents
+    must appear in the same order as the output clocks.
+  - #clock-cells: Must be 1
+  - clock-output-names: The name of the clocks as free-form strings
+  - renesas,indices: Indices of the gate clocks into the group (0 to 31)
+
+The clocks, clock-output-names and renesas,indices properties contain one
+entry per gate clock. The MSTP groups are sparsely populated. Unimplemented
+gate clocks must not be declared.
+
+
+Example
