-* 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>;
