Merge tag 'imx-drm-fixes-2017-06-08' of git://git.pengutronix.de/git/pza/linux into drm-fixes
imx-drm: PRE clock gating, panelless LDB, and VDIC CSI selection fixes - Keep the external clock input to the PRE ungated and only use the internal soft reset to keep the module in low power state, to avoid sporadic startup failures. - Ignore -ENODEV return values from drm_of_find_panel_or_bridge in the LDB driver to fix probing for devices that still do not specify a panel in the device tree. - Fix the CSI input selection to the VDIC. According to experiments, the real behaviour differs a bit from the documentation. * tag 'imx-drm-fixes-2017-06-08' of git://git.pengutronix.de/git/pza/linux: gpu: ipu-v3: Fix CSI selection for VDIC drm/imx: imx-ldb: Accept drm_of_find_panel_or_bridge failure gpu: ipu-v3: pre: only use internal clock gating
