Subject: [PATCH 2/8] soc: Add MediaTek pericfg controller support
Date: Tue, 20 Jan 2015 10:47:05 +0100	[thread overview]
Message-ID: <1421747231-554-3-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1421747231-554-1-git-send-email-s.hauer@pengutronix.de>

This adds support for the MediaTek pericfg controller found
on the MT8135/MT8173 SoCs. The pericfg controller contains
miscellaneous registers for controlling peripheral resets and
clocks.

+MediaTek pericfg Controller
+
+The pericfg controller contains miscellaneous registers for controlling
+clocks, resets and bus settings.
+
+Required properties:
+- compatible: must be one of:
+	mediatek,mt8135-pericfg
+	mediatek,mt8173-pericfg
+- reg: Address range for the pericfg controller
+
+Example:
+
+	pericfg: pericfg@10003000 {
+		#reset-cells = <1>;
+		#clock-cells = <1>;
+		compatible = "mediatek,mt8135-pericfg";
+		reg = <0 0x10003000 0 0x1000>;
+	};
