This short series covers two subsystems and implements support for suspend and resume operations on the DU pipelines on Gen3 Rcar platforms.
Patch 1: Prevent resuming DRM pipelines, - Ensures that the VSP does not incorrectly start DU pipelines.
Patch 2: Add suspend resume helpers - Makes use of the atomic helper functions to control the CRTCs and fbdev emulation.
Patch 3: Remove unused CRTC suspend/resume functions - Cleans up some old, related but unused functions that are not necessary to keep in the code base.
Whilst this is posted as a single series, there are no hard dependencies between any of the three patches. They can be picked up independently as and when they are successfully reviewed.
This series can be fetched from the following:
git://git.kernel.org/pub/scm/linux/kernel/git/kbingham/rcar.git tags/vsp-du/du-suspend-resume/v1
It is based upon a merge of both the current linux-media master branch and the DRM drm-next tree.
