Optional Properties:

- always-running: If the watchdog timer cannot be disabled, add this flag to

  have the driver keep toggling the signal without a client. It will only cease

  to toggle the signal when the device is open and the timeout elapsed.

*ImgTec PowerDown Controller (PDC) Watchdog Timer (WDT)



Required properties:

- compatible : Should be "img,pdc-wdt"

- reg : Should contain WDT registers location and length

- clocks: Must contain an entry for each entry in clock-names.

- clock-names: Should contain "wdt" and "sys"; the watchdog counter

               clock and register interface clock respectively.

- interrupts : Should contain WDT interrupt



Examples:



watchdog@18102100 {

	compatible = "img,pdc-wdt";

	reg = <0x18102100 0x100>;

	clocks = <&pdc_wdt_clk>, <&sys_clk>;
