[PATCH 0/6] drm/fsl-dcu: suspend/resume rework using atomic helpers

From: Stefan Agner
Date: Tue Apr 19 2016 - 13:54:17 EST


This implements suspend/resume using the atomic update supsend/resume
helpers instead of the current implementation which uses regcache. The
code has been tested on a Colibri VF61 using the freeze suspend mode.

This also avoids a lockdep warning by not using register caching at
all and therefor obsoletes this patch:
