[PATCH v9 1/5] Documentation: add sbsa-gwdt driver documentation

2015-11-08 Thread fu . wei 
From: Fu Wei 

The sbsa-gwdt.txt documentation in devicetree/bindings/watchdog is for
introducing SBSA(Server Base System Architecture) Generic Watchdog
device node info into FDT.

Also add sbsa-gwdt introduction in watchdog-parameters.txt
