* 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 = <GIC_SPI 72 IRQ_TYPE_EDGE_RISING>;
|
|
clocks = <&rtc32k_xtal>;
|
|
vdd-supply = <&rtc_vdd>;
|
|
resets = <&reset RESET_RTC>;
|
|
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
};
