[PATCH 1/2] devicetree: Document generic watchdog properties

[Timo Kokkonen <timo.kokkonen@offcode.fi>]

There is no documentation for the watchdog properties that are common
among most of the watchdog drivers. Add document where these generic
properties can be described and told how they should be used in
drivers. Start from the "timeout-sec" property.
