Subject: [PATCH v7 6/7] ARM: rockchip: add power-management-unit
Date: Mon, 20 Jan 2014 16:45:44 +0100	[thread overview]
Message-ID: <4432410.A9WRey4k7t@phil> (raw)
In-Reply-To: <4970034.fqvMoHdOyd@phil>

The pmu is needed to bring up the cores during smp operations and later
also other system parts. Therefore add a node and documentation for it.

+Rockchip power-management-unit:
+-------------------------------
+
+The pmu is used to turn off and on different power domains of the SoCs
+This includes the power to the CPU cores.
+
+Required node properties:
+- compatible value : = "rockchip,rk3066-pmu";
+- reg : physical base address and the size of the registers window
+
+Example:
+
+	pmu@20004000 {
+		compatible = "rockchip,rk3066-pmu";
+		reg = <0x20004000 0x100>;
