[RESEND 0/5] drm/mxsfb: Fix runtime PM for unpowering lcdif block

From: Leonard Crestez

Adding lcdif nodes to a power domain currently doesn't work, it results
in black/corrupted screens or hangs. While the driver does enable
runtime pm it does not deal correctly with the block being unpowered.

All patches in this series have review tags from a few weeks ago. I'm
resending this today because 4.19 rc1 was released. I'm not sure if this
matters for DRM but in some areas unrelated series get lost during the
merge window.

Marek/Phillip: Is one of you going to pick up these patches?
