+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";
+};
