Thanks for your patch!

Missing IMPA0?
Or is it internal-only? Perhaps the same for IMPA1 below?

Missing VIOBUS? You do have it as an internal core clock.

> +#define R8A779G0_CLK_VIOBUSD2          60

Missing VCBUS? You do have it as an internal core clock.

Missing IMPA?
Figure 8.1.1 (Block Diagram of CPG) indicates it's a direct
input to the IMP block, hence not an internal core clock.

when I'm talking to journalists I just say "programmer" or something like that.
