Add all R-Car M3-W Clock Pulse Generator Core Clock Outputs, as listed
in Table 8.2b ("List of Clocks [R-Car M3-W]") of the R-Car Gen3
datasheet (rev. 0.51 + Errata for Rev051 Mar 31 2016).

Note that internal CPG clocks (S0, S1, S2, S3, SDSRC, and SSPSRC) are
not included, as they are used as internal clock sources only, and never
referenced from DT.

I think we recently started a discussion to find a more clever way to
avoid re-defining (copy & paste) all this R-Car3 clocks  (compare [1])
where they are the same over the R-Car3 family while still being able to
deal with the differences.

Best regards

Dirk

What's the status of the discussion I mentioned above?


Best regards
