+Conexant Digicolor SoCs Timer Controller
+
+Required properties:
+
+- compatible : should be "cnxt,cx92755-timer"
+- reg : Specifies base physical address and size of the MISC area, that is
+ where the "Agent Communication" registers are located
+- interrupts : Contains 8 interrupts, one for each timer
+- clocks: phandle to the main clock
+
+Example:
+
+ timer@f0000000 {
+ compatible = "cnxt,cx92755-timer";
+ reg = <0xf0000000 0x1000>;
+ interrupts = <19>, <31>, <34>, <35>, <52>, <53>, <54>, <55>;
