Cadence TTC - Triple Timer Counter



Required properties:

- compatible : Should be "cdns,ttc".

- reg : Specifies base physical address and size of the registers.

- interrupts : A list of 3 interrupts; one per timer channel.

- clocks: phandle to the source clock



Optional properties:

- timer-width: Bit width of the timer, necessary if not 16.



Example:



ttc0: ttc0@f8001000 {

	interrupt-parent = <&intc>;

	interrupts = < 0 10 4 0 11 4 0 12 4 >;

	compatible = "cdns,ttc";

	reg = <0xF8001000 0x1000>;

	clocks = <&cpu_clk 3>;

	timer-width = <32>;

};
