+Device-Tree bindings for Power Device on MediaTek PMIC RTC
+
+The power device is responsible for externally power off or on the remote
+MediaTek SoC through the a tiny circuit block BBPU inside PMIC RTC.
+
+Required parent node:
+- rtc
+ For MediaTek PMIC RTC bindings, see:
+ Documentation/devicetree/bindings/mfd/mt6397.txt
+
+Required properties:
+- compatible: Should be one of follows
+ "mediatek,mt6323-rtc-poweroff": for MT6323 PMIC
+ "mediatek,mt6397-rtc-poweroff": for MT6397 PMIC
+
+Example:
+
+ rtc {
+ compatible = "mediatek,mt6323-rtc";
+
+ power-off {
+ compatible = "mediatek,mt6323-rtc-poweroff";
+ };
+ };
