ARM AMBA Primecell SP805 Watchdog



Required properties:

- compatible: Should be "arm,sp805" & "arm,primecell"

- reg: Should contain location and length for watchdog timer register.

- interrupts: Should contain the list of watchdog timer interrupts.

- clocks: clocks driving the watchdog timer hardware. This list should be 2

	clocks. With 2 clocks, the order is wdogclk clock, apb_pclk.



Example:

	watchdog@66090000 {

		compatible = "arm,sp805", "arm,primecell";

		reg = <0x66090000 0x1000>;

		interrupts = <GIC_SPI 406 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&apb_pclk>,<&apb_pclk>;

		clock-names = "wdogclk", "apb_pclk";

	};
