[PATCH v4 07/16] ARM: shmobile: r8a7778 dtsi: Add CPG/MSTP Clock Domain

From: Geert Uytterhoeven
Date: Tue Aug 04 2015 - 08:31:44 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. A notable
exception is the "sound" node, which represents multiple SoC devices,
each having their own MSTP clocks.
