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 , semantics where 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. BR, Alexey
