-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>;
-};

-...
-	clocks = <&hym8563>;
