Hi,
The following two fixes make sure that suspend/resume works again for the Freescale DCU driver:
9306e996574f ("drm/fsl-dcu: avoid disabling pixel clock twice on suspend") 9fd99f4f3f5e ("drm/fsl-dcu: enable IRQ before drm_atomic_helper_resume()")
It would be good if they make it into v4.14 sometime.
