0001 * Amlogic Meson6, Meson8, Meson8b and Meson8m2 RTC
0002
0003 Required properties:
0004 - compatible: should be one of the following describing the hardware:
0005 * "amlogic,meson6-rtc"
0006 * "amlogic,meson8-rtc"
0007 * "amlogic,meson8b-rtc"
0008 * "amlogic,meson8m2-rtc"
0009
0010 - reg: physical register space for the controller's memory mapped registers.
0011 - interrupts: the interrupt line of the RTC block.
0012 - clocks: reference to the external 32.768kHz crystal oscillator.
0013 - vdd-supply: reference to the power supply of the RTC block.
0014 - resets: reset controller reference to allow reset of the controller
0015
0016 Optional properties for the battery-backed non-volatile memory:
0017 - #address-cells: should be 1 to address the battery-backed non-volatile memory
0018 - #size-cells: should be 1 to reference the battery-backed non-volatile memory
0019
0020 Optional child nodes:
0021 - see ../nvmem/nvmem.txt
0022
0023 Example:
0024
0025 rtc: rtc@740 {
0026 compatible = "amlogic,meson6-rtc";
0027 reg = <0x740 0x14>;
0028 interrupts = <GIC_SPI 72 IRQ_TYPE_EDGE_RISING>;
0029 clocks = <&rtc32k_xtal>;
0030 vdd-supply = <&rtc_vdd>;
0031 resets = <&reset RESET_RTC>;
0032
0033 #address-cells = <1>;
0034 #size-cells = <1>;
0035 };
