-Required properties:
-- compatible      :  "rda,8810pl-timer"
-- reg             :  Offset and length of the register set for the device.
-- interrupts      :  Should contain two interrupts.
-- interrupt-names :  Should be "hwtimer", "ostimer".

-Example:
-
-		apb@20900000 {

-			...
-			timer@10000 {
-				compatible = "rda,8810pl-timer";
