+Device-Tree bindings for MediaTek PMIC based RTC
+
+MediaTek PMIC based RTC is an independent function of MediaTek PMIC which
+is working as a multi-function device (MFD). And the RTC can be configured and
+set up via PMIC wrapper bus. Which is also common resource shared among the
+other functions present on the PMIC.
+
+For MediaTek PMIC wrapper bus bindings, see:
+Documentation/devicetree/bindings/soc/mediatek/pwrap.txt
+
+Required parent node:
+- pmic
+ For MediaTek PMIC MFD bindings, see:
+ Documentation/devicetree/bindings/mfd/mt6397.txt
+
+Required properties:
+- compatible: Should be one of follows
+ "mediatek,mt6323-rtc": for MT6323 PMIC
+ "mediatek,mt6397-rtc": for MT6397 PMIC
+
+Optional child node:
+- power-off
+ For Power-Off Device for MediaTek PMIC RTC bindings, see:
+ Documentation/devicetree/bindings/power/reset/mt6397-rtc-poweroff.txt
+
+Example:
+
+ pmic {
+ compatible = "mediatek,mt6323";
+
+ ...
+ rtc {
+ compatible = "mediatek,mt6323-rtc";
+
+ power-off {
+ compatible = "mediatek,mt6323-rtc-poweroff";
+ };
+ };
+};
