Thank you for the comments. Yes, I did so in v1-v3, but after rethinking
about the situation (Actually both the HW version and the clock mux itself
are same, just the clock sources connecting to the mux might be different),
so I decided to do this by abstracting the driver from those source info
and letting DT binding to pass such information. Because I think putting
the clock sources into the driver differed by compatible value would make
the driver more like SoC-specified, not the ideal way -- SoC-independent,
since the clock sources are based on SoC design, not on itself.
