[PATCH 0/4] Fix DP busy wait and defer disabling overlay plane

[Dan MacDonald]

I should've said that 4.10 didn't pause at:

[ 4.458572] panel-simple panel-lcd: panel-lcd supply power not found,
using dummy regulator
[ 4.467736] panel-simple panel-lvds0: panel-lvds0 supply power not
found, using dummy regulator

If it showed those lines at all and I've never seen those flip_done
errors before.

This revision of the patch has made my SL's display situation worse as
I'm not getting any HDMI output now.

PS I should have another go at getting cross-compiling to work.
Failing that, I'll buy an Odroid or something and build stuff in a
chroot. 11 hour builds are a bit much!

Thanks
