I think you can now remove the dispc_mgr_go() from dpi.c in this patch.
And something else, which doesn't need to be fixed now, but just to
point out: dpi_set_timings() currently uses runtime_get to enable the
HW. If everything was in proper shape, this wouldn't be needed.
dpi_set_timings() would call apply.c's functions, and if the output is
disabled, the settings would just be stored in ram. So there wouldn't be
any need to enable the HW with runtime_get().
Then again, if we do change clock settings or non-shadow registers in
dpi_set_timings(), then that's not possible (at least via apply.c's
caching system).
