1* Amlogic Meson6, Meson8, Meson8b and Meson8m2 RTC
 2
 3Required properties:
 4- compatible: should be one of the following describing the hardware:
 5	* "amlogic,meson6-rtc"
 6	* "amlogic,meson8-rtc"
 7	* "amlogic,meson8b-rtc"
 8	* "amlogic,meson8m2-rtc"
 9
10- reg: physical register space for the controller's memory mapped registers.
11- interrupts: the interrupt line of the RTC block.
12- clocks: reference to the external 32.768kHz crystal oscillator.
13- vdd-supply: reference to the power supply of the RTC block.
14- resets: reset controller reference to allow reset of the controller
15
16Optional properties for the battery-backed non-volatile memory:
17- #address-cells: should be 1 to address the battery-backed non-volatile memory
18- #size-cells: should be 1 to reference the battery-backed non-volatile memory
19
20Optional child nodes:
21- see ../nvmem/nvmem.txt
