-Faraday Technology FTWDT010 watchdog
-
-This is an IP part from Faraday Technology found in the Gemini
-SoCs and others.
-
-Required properties:
-- compatible : must be one of
-  "faraday,ftwdt010"
-  "cortina,gemini-watchdog", "faraday,ftwdt010"
-- reg : shall contain base register location and length
-- interrupts : shall contain the interrupt for the watchdog
-
-Optional properties:
-- timeout-sec : the default watchdog timeout in seconds.
-
-Example:
-
-watchdog@41000000 {
-	compatible = "faraday,ftwdt010";
-	reg = <0x41000000 0x1000>;
-	interrupts = <3 IRQ_TYPE_LEVEL_HIGH>;
-};
