As long as we're consistently inconsistent... What about 4210 and 4x12?
Hopefully, the reason was to avoid breaking them.
This creates horrible incompatibilities between dts and kernel versions
by changing both. Any prior kernel will not work with this dts or later.
And more importantly this kernel version or newer will not work with
existing dtb's. We've been pretty lax on this as DT support has been
under heavy development, but things need to start tightening up. That
being said, if this isn't yet a concern for this platform, then I don't
really care.
