+* Amlogic Meson6, Meson8, Meson8b and Meson8m2 RTC
+
+Required properties:
+- compatible: should be one of the following describing the hardware:
+	* "amlogic,meson6-rtc"
+	* "amlogic,meson8-rtc"
+	* "amlogic,meson8b-rtc"
+	* "amlogic,meson8m2-rtc"
+
+- reg: physical register space for the controller's memory mapped registers.
+- interrupts: the interrupt line of the RTC block.
+- clocks: reference to the external 32.768kHz crystal oscillator.
+- vdd-supply: reference to the power supply of the RTC block.
+- resets: reset controller reference to allow reset of the controller
+
+Optional properties for the battery-backed non-volatile memory:
+- #address-cells: should be 1 to address the battery-backed non-volatile memory
+- #size-cells: should be 1 to reference the battery-backed non-volatile memory
+
+Optional child nodes:
+- see ../nvmem/nvmem.txt
+
+Example:
+
+	rtc: rtc@740 {
+		compatible = "amlogic,meson6-rtc";
+		reg = <0x740 0x14>;
+		interrupts = <GIC_SPI 72 IRQ_TYPE_EDGE_RISING>;
+		clocks = <&rtc32k_xtal>;
+		vdd-supply = <&rtc_vdd>;
+		resets = <&reset RESET_RTC>;
+
+		#address-cells = <1>;
+		#size-cells = <1>;
+	};
