+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
+- interrupts: rtc alarm/event interrupt
+- #clock-cells: the value should be 0
+
+Optional properties:
+- clock-output-names: From common clock binding
+
+Example:
+
+hym8563: hym8563@51 {
+       compatible = "haoyu,hym8563";
+       reg = <0x51>;
+
+       interrupts = <13 IRQ_TYPE_EDGE_FALLING>;
+
+       #clock-cells = <0>;
+};
+
+device {
+...
+       clocks = <&hym8563>;
+...
+};
