Subject: [PATCH] dt-bindings: watchdog: convert faraday,ftwdt010 to yaml
Converts watchdog/faraday,ftwdt010.txt to yaml.
This permits to detect missing properties like clocks and resets or
compatible like moxa,moxart-watchdog.

-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@...00000 {
- compatible = "faraday,ftwdt010";
- reg = <0x41000000 0x1000>;
- interrupts = <3 IRQ_TYPE_LEVEL_HIGH>;
-};
