+NVIDIA Tegra20 timer
+
+The Tegra20 timer provides four 29-bit timer channels and a single 32-bit free
+running counter. The first two channels may also trigger a watchdog reset.
+
+Required properties:
+
+- compatible : should be "nvidia,tegra20-timer".
+- reg : Specifies base physical address and size of the registers.
+- interrupts : A list of 4 interrupts; one per timer channel.
+- clocks : Must contain one entry, for the module clock.
+  See ../clocks/clock-bindings.txt for details.
+
+Example:
+
+timer {
+       compatible = "nvidia,tegra20-timer";
+       reg = <0x60005000 0x60>;
+       interrupts = <0 0 0x04
+                       0 1 0x04
+                       0 41 0x04
+                       0 42 0x04>;
+       clocks = <&tegra_car 132>;
+};
