+Device-Tree bindings for MediaTek SoC based RTC
+
+Required properties:
+- compatible : Should be
+ "mediatek,mt7622-rtc", "mediatek,soc-rtc" : for MT7622 SoC
+- reg : Specifies base physical address and size of the registers;
+- interrupts : Should contain the interrupt for RTC alarm;
+- clocks : Specifies list of clock specifiers, corresponding to
+ entries in clock-names property;
+- clock-names : Should contain "rtc" entries
+
+Example:
+
+rtc: rtc@10212800 {
+ compatible = "mediatek,mt7622-rtc",
+ "mediatek,soc-rtc";
+ reg = <0 0x10212800 0 0x200>;
+ interrupts = <GIC_SPI 129 IRQ_TYPE_LEVEL_LOW>;
+ clocks = <&topckgen CLK_TOP_RTC>;
+ clock-names = "rtc";
+};
