Have a 12 MHz fixed CEC clock source connected to the CEC_CLK pin
on ADV7511:
  - r8a7790/lager
  - r8a7791/koelsch
  - r8a7791/porter
  - r8a7792/blanche
  - r8a7793/gose
  - r8a7794/alt
  - r8a7794/silk

I don't know about r8a7792/wheat. But according to its .dts file, it has two
instances of the ADV7513, not ADV7511.

Gr{oetje,eeting}s,

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
