+* Renesas H8/300 Timer Pluse Unit
+
+The TPU is a 16bit timer/counter with configurable clock inputs and
+programmable compare match.
+This implementation support only cascade mode.
+
+Required Properties:
+
+  - compatible: must contain "renesas,tpu"
+  - reg: base address and length of the registers block in 2 channel.
+  - clocks: a list of phandle, one for each entry in clock-names.
+  - clock-names: must contain "peripheral_clk" for the functional clock.
+
+
+Example:
+       tpu: tpu@ffffe0 {
+               compatible = "renesas,tpu";
+               reg = <0xffffe0 16>, <0xfffff0 12>;
+               clocks = <&pclk>;
+               clock-names = "peripheral_clk";
+       };
