[PATCH/RFC 3/5] ARM: shmobile: r8a7791 dtsi: Add CPG Clock Domain
Geert Uytterhoeven
geert+renesas at glider.be
Wed Mar 18 12:46:55 PDT 2015
Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG Clock Domain.
Add "power-domains" properties to all device nodes for devices that are
part of the CPG Clock Domain and can be power-managed through their
primary clock. This includes most on-SoC devices. Notable exceptions
are:
- du, which references 3 or 5 clocks; I assume the driver manages all
of them itself?
- rcar_sound, which references lots of clock; idem?
