During testing the DCU DRM driver on the Freescale Vybrid platform I came across some (platform independent) bugs and problems which this patchset addresses.
Note: To use the driver on Vybrid some platform/device-tree enhancements are needed which are not part of this patchset. I still need to clean those up.
Stefan Agner (7): drm/fsl-dcu: specify volatile registers drm/fsl-dcu: remove regmap return value checks drm/fsl-dcu: avoid memory leak on errors drm/fsl-dcu: handle initialization errors properly drm/fsl-dcu: mask all interrupts on initialization drm/fsl-dcu: fix alpha blending drm/fsl-dcu: use mode flags for hsync/vsync pixelclk polarity
