5- reg: Should contain location and length for watchdog timer register.
6- interrupts: Should contain the list of watchdog timer interrupts.
7- clocks: clocks driving the watchdog timer hardware. This list should be 2
8 clocks. With 2 clocks, the order is wdogclk clock, apb_pclk.

12 compatible = "arm,sp805", "arm,primecell";
13 reg = <0x66090000 0x1000>;
14 interrupts = <GIC_SPI 406 IRQ_TYPE_LEVEL_HIGH>;
15 clocks = <&apb_pclk>,<&apb_pclk>;
