If the tvmixer module is also available in SoC's prior to Exynos4210,
and if tvmixer in Exynos4210 is similar to tvmixer found on prior
SoC's, the base version should indicate that. For instance, if the
tvmixer started to appear from s5pv210 onwards, then the compatible
value should be "samsung,s5pv210-tvmixer". The compatible string
should indicate the base version.

Fair point, although I'm afraid that chosing "base" version might be
tricky sometimes (e.g. while g2d seems to be available on s5pv210 driver
itself have been tested only on s5pv310/exynos4210 - chosing s5pv210 as
base doesn't look like best idea.)

I'll resend fixed patches later.

Thank you very much for review!
