Simon,
I should be able to give this a test drive on the RK3368 by the end of the week.
For the RK3399 our board uses full OF_CONTROL, so I won’t really exercise
this there.
Given that the RK3399 can always fall back to OF_CONTROL for SPL (as is the
default on Puma) and this only blocks the RK3368 TPL (which is not enabled
for any other boards than Lion): should we try to get this merged for this release
cycle or let it slip into the new merge window?
Regards,
Philipp.
