* 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 = ; clocks = <&rtc32k_xtal>; vdd-supply = <&rtc_vdd>; resets = <&reset RESET_RTC>; #address-cells = <1>; #size-cells = <1>; };
