* 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
