First question - yes, look for both properties. Using the existing
property is even better, I don't mind at all. Thanks for pointing that
out.

Initially, I added more generic samsung,... property because I thought
that device tree style prefers <vendor>,<property-name> semantics where
<vendor> is actual (real) HW vendor of corresponding hw block and it
should also refer to the first/earlier hw vendor in terms of the
timeline.

Using google,<..> is simplier and I don't need need commit that
obsoletes that, so I'll rework the series in that way.
