On our device the LCD panel is powered by one of the ACT8600 outputs.
Avoiding the deferred probe means the screen turns on a couple of
seconds earlier.
I agree that the current hardcoded priority system is not ideal and a
dependency based system would be the right solution in the long term,
but I was looking for a short term solution with this patch.
In any case, I excluded this patch from the v2 series. I cleaned up the
register configuration (debugfs) patch, split the of_node patch into two
patches and resubmitted the redundant dev lookups patch. Thanks for
reviewing and please let me know if there is anything more that needs
changing.
