[PATCH 01/22] ARM: dts: r8a7743: Add reset control properties

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add properties to describe the reset topology for on-SoC devices:
  - Add the "#reset-cells" property to the CPG/MSSR device node,
  - Add resets and reset-names properties to the various device nodes.

This allows to reset SoC devices using the Reset Controller API.

Note that all resets added match the corresponding module clocks.

[PATCH 12/22] ARM: dts: r8a7792: Correct Z clock

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Unlike other R-Car Gen2 SoCs with Cortex-A15 CPU cores, R-Car V2H does
not have a programmable Z clock (Cortex-A15 CPU core clock), but uses a
fixed divider.
This is similar to the Z2 clock (Cortex-A7 CPU core clock) on R-Car E2.

Hence:
  - Remove the Z clock output from the cpg_clocks node, as this implied
    a programmable clock,
  - Add the Z clock as a fixed factor clock,
  - Let the first CPU node point to the new Z clock,
  - Remove the Z clock index from the bindings (this definition was used
    by r8a7792.dtsi only, and was not a contract between DT and driver).

[PATCH 13/22] ARM: dts: r8a7794: Add Z2 clock

[Simon Horman]

From: Geert Uytterhoeven <geert+renesas@glider.be>

Add the Z2 clock (Cortex-A7 CPU core clock), which uses a fixed divider,
and link the first CPU node to it.
