Merge branch 'for-next' of http://git.agner.ch/git/linux-drm-fsl-dcu into drm-next
This adds drm bridge support for the NXP/Freescale DCU. The patchset has been discussed on the mailing list since quite some time... Plus there is a small fix provided by Peter. * 'for-next' of http://git.agner.ch/git/linux-drm-fsl-dcu: drm/fsl-dcu: add support for drm bridge drm/fsl-dcu: rework codes to support of_graph dt binding for panel drm/fsl-dcu: add missing of_node_put after calling of_parse_phandle
