Subject: [PATCH v2 01/17] dt-bindings: power: reset: mt6323: add bindings for MT6323 power controller

From: Sean Wang <sean.wang@...iatek.com>

Adding device-tree binding for the power controller which is a tiny
circuit block present as a part of MT6323 PMIC and is responsible for
externally powering off or on a remote SoC the PMIC is connected to.

+Device Tree Bindings for Power Controller on MediaTek PMIC
+
+The power controller which could be found on PMIC is responsible for externally
+powering off or on the remote MediaTek SoC through the circuit BBPU.
+
+Required properties:
+- compatible: Should be one of follows
+	"mediatek,mt6323-pwrc": for MT6323 PMIC
+
+Example:
+
+	pmic {
+		compatible = "mediatek,mt6323";
+
+		...
+
+		power-controller {
+			compatible = "mediatek,mt6323-pwrc";
+		};
+	}
