From 7b9ad9a0ab82be3cb0607d5242584a4a4948e89c Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 17 Feb 2015 16:43:02 +0100 Subject: [PATCH] ARM: shmobile: r8a73a4 dtsi: Add PM domain support 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. The System Controller is also used by the R-Mobile Reset driver, which can now restart the system.
