| * 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 |

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