[PATCH v3 12/16] ARM: shmobile: r8a7794 dtsi: Add CPG/MSTP Clock Domain

From: Geert Uytterhoeven
Date: Wed Jul 01 2015 - 12:02:07 EST


Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock. This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.

v3:
- Use "CPG/MSTP Clock Domain" instead of "CPG Clock Domain",

v2:
- Add Reviewed-by,
- Add "power-domains" properties to recently introduced USB-DMAC
device nodes,
- Drop adding "power-domains" properties to the GIC device node, as
adding the INTC_SYS clock is postponed.
