Guenter,

My issue regarding the vendor prefix was not a hard dissagreement but
was more about me understanding the rational behind using vendor
prefixes. In this case the imx2_wdt driver 'is' a vendor specific
driver as its compatible strings are prefixed with 'fsl,' so isn't
'any' property added to devicetree/bindings/watchdog/fsl-imx-wdt.txt
inherently a vendor specific properly already? I assume that is why
the 'big-endian' property isn't 'fsl,big-endian'.

Maybe it's more about if it 'is' marked as a vendor specific property
its much easier to get approval and accepted by a vendor-specific
maintainer?

Shawn,

Sure - I'll rebase and re-submit.
