Good Evening,

While I'm not against this idea, my main concern still stands.
I spent a great deal of thought on this, and decided to go the route I
did to maintain consistency with previous generations.
As such, I see one of three paths here:
- Pull this patch only and depart rk356x from previous SoCs.
- Do the same for previous SoCs to maintain consistency.
- Drop this patch to maintain consistency with previous SoCs.

I ask that others weigh in here, as offline discussion has produced
mixed results already.

Thanks,
Peter
