Haoyu Microelectronics HYM8563 Real Time Clock



The HYM8563 provides basic rtc and alarm functionality

as well as a clock output of up to 32kHz.



Required properties:

- compatible: should be: "haoyu,hym8563"

- reg: i2c address

- #clock-cells: the value should be 0



Optional properties:

- clock-output-names: From common clock binding

- interrupts: rtc alarm/event interrupt



Example:



hym8563: hym8563@51 {

	compatible = "haoyu,hym8563";

	reg = <0x51>;



	interrupts = <13 IRQ_TYPE_EDGE_FALLING>;



	#clock-cells = <0>;

};



device {

...

	clocks = <&hym8563>;

...

};
