There is a bug in the setting of the DES (Display Enable Signal) register. This current setting occurs 1 dot left shift. The DES register should be set minus one value about the specifying value with H/W specification. This patch corrects it. Signed-off-by:

It isn't safe to call drm_dev_unregister() without first initializing mode setting with drm_mode_config_init(). This leads to a crash if either IO memory can't be remapped or vblank initialization fails. Fix this by reordering the initialization sequence. Move vblank initialization after the drm_mode_config_init() call, and move IO remapping before drm_dev_alloc() to avoid the need to perform clean up in case of failure. While at it remove the explicit drm_vblank_cleanup() call from rcar_du_remove() as the drm_dev_unregister() function already cleans up vblank. Signed-off-by: -

When an encoder fails to initialize the driver prints an error message to the kernel log. The message contains the name of the encoder's DT node, which is NULL for internal encoders. Use the of_node_full_name() macro to avoid dereferencing a NULL pointer, print the output number to add more context to the error, and make sure we still own a reference to the encoder's DT node by delaying the of_node_put() call.

Here is the list of fixes that I have for drm/mali-dp. They've been on the mailing lists for a while and merged into linux-next for a few weeks, but due to holiday and travel to Linux Plumbers I did not send the pull request earlier. I don't know if these patches can be pulled into v4.9 still (they will conflict with Ville Syrjälä's cleanup of DRM_ROTATE series that is already in drm-next), but if you do that would be great. * 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld: drm: mali-dp: Clear CVAL when leaving config mode drm/arm: mark symbols static where possible drm: mali-dp: Add support for setting plane's rotation property from userspace. drm: mali-dp: Don't set DRM_PLANE_COMMIT_ACTIVE_ONLY drm: mali-dp: Store internal format and n_planes in plane state drm: mali-dp: Enable alpha blending drm: mali-dp: Refactor plane initialisation arm: mali-dp: Extract mode_config cleanup into malidp_fini drm: mali-dp: Add pitch alignment check for planes drm: mali-dp: Add pitch alignment check function drm: mali-dp: Set the drm->irq_enabled flag to match driver's state. drm: mali-dp: Clear the config_valid flag before using it in wait_event.
