Makes sense. I understand the need to reuse and I need a bit of time to
have a look at the code(both Amlogic one's you have pointed out and the
Rockchip one) in detail to see what's the best way to proceed. I will
have a look at this later this week and get back to you.

Yes I tried checking with Rockchip but didn't get a response. But my
guess is that it was some preliminary unpublished version of SCPI
unfortunately :(
