+RDA Micro RDA8810PL Timer
+
+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 {
+                       compatible = "simple-bus";
+                       ...
+                       timer@10000 {
+                               compatible = "rda,8810pl-timer";
+                               reg = <0x10000 0x1000>;
+                               interrupts = <16 IRQ_TYPE_LEVEL_HIGH>,
+                                            <17 IRQ_TYPE_LEVEL_HIGH>;
+                               interrupt-names = "hwtimer", "ostimer";
