[PATCH 2/3] ARM: shmobile: r8a73a4 dtsi: Add PM domain support
Geert Uytterhoeven
geert+renesas at glider.be
Wed Feb 4 05:52:45 PST 2015
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.
