Describe the RPCSRC internal clock and the RPC[D2] clocks derived from it,
as well as the RPC-IF module clock, in the R-Car H3 (R8A7795) CPG/MSSR
driver.

Inspired by commit 94e3935b5756 ("clk: renesas: r8a77980: Add RPC clocks").

Thanks for your patch!

Before I queue this in clk-renesas-for-v5.7: given the fuzz with the RPC
driver, has this been tested successfully?

On a custom r8a7796 with 64MB Hyperflash attached I can read and write 
it via /dev/mtdx. Read data looks ok. Write data is byte swapped, but 
this is definitely a big-/little-endian driver issue. And not a clock one ;)

Best regards

Dirk
