This extends the device tree bindings for the Faraday FTWDT010 block to cover: - The "moxa,moxart-watchdog" compatible version - The "aspeed,ast2400-wdt" and "aspeed,ast2500-wdt" versions - clocks (PCLK non-optional, the Gemini also have this now) - reset line (optional, exist on the Gemini) - configuration to use the external clock (faraday,use-extclk) Cc: devicetree-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Signed-off-by: Linus Walleij <redacted> --- .../devicetree/bindings/watchdog/faraday,ftwdt010.txt | 16 ++++++++++++++-- 1 file changed, 14 insertions(+), 2 deletions(-)
