+Allwinner SoCs High Speed Timer Controller
+
+Required properties:
+
+- compatible : should be "allwinner,sun5i-a13-hstimer" or
+               "allwinner,sun7i-a20-hstimer"
+- reg : Specifies base physical address and size of the registers.
+- interrupts : The interrupts of these timers (2 for the sun5i IP, 4 for the sun7i
+               one)
+- clocks: phandle to the source clock (usually the AHB clock)
+
+Optionnal properties:
+- resets: phandle to a reset controller asserting the timer
+
+Example:
+
+timer@01c60000 {
+       compatible = "allwinner,sun7i-a20-hstimer";
+       reg = <0x01c60000 0x1000>;
+       interrupts = <0 51 1>,
+                    <0 52 1>,
+                    <0 53 1>,
+                    <0 54 1>;
+       clocks = <&ahb1_gates 19>;
+       resets = <&ahb1rst 19>;
+};
