[PATCH v4 8/9] ARM: shmobile: r8a7740 dtsi: Add PM domain support

From: Geert Uytterhoeven
Date: Mon Nov 03 2014 - 10:36:51 EST

Add a device node for the System Controller, with subnodes that
represent the hardware power area hierarchy.
Hook up all devices to their respective PM domains.

Add a minimal device node for the Coresight-ETM hardware block, and hook
it up to the D4 PM domain, so the R-Mobile System Controller driver can
keep the domain powered, until the new Coresight code handles runtime
PM.

Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
---
v4:
- Remove power-domains properties from clocks, as these will not be
instantiated as platform devices,
- Fix indentation of power-domains property in pfc node,
- Add minimal node for Coresight-ETM,
- Add power-domains properties to the recently added TMU nodes,
v3:
- Move power-on/off latencies to a separate patch,
- Add dependencies,
v2:
- Insert power-domains property after clock-names property in the cmt1
node.
