You should clarify the compatible list here: It seems that the devices are fully
compatible, so the driver should only need to check for "ti,davinci-wdt" as the
compatible string, while the dtb files should list both "ti,davinci-wdt" and
"ti,keystone-wdt" for keystone, but only the davinci string for davinci.
