Merge branch 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld into drm-next

I have accumulated some patches as we went through some internal testing
for mali-dp and I was waiting for the YUV2RGB patches to land in your
tree.

* 'for-upstream/mali-dp' of git://linux-arm.org/linux-ld:
  drm: mali-dp: Add YUV->RGB conversion support for video layers
  drm: mali-dp: Turn off CRTC vblank when removing module.
  drm: arm: malidp: Use drm_atomic_helper_shutdown() to disable planes on removal
  drm: arm: malidp: Don't destroy planes manually in error handlers
  drm/mali-dp: Fix malidp_atomic_commit_hw_done() for event sending.
  drm/arm/malidp: Disable pixel alpha blending for colors that do not have alpha
  drm: mali-dp: Fix bug on scaling with rotation
  drm/mali-dp: Don't enable scaling engine for planes that only rotate.
  drm: mali-dp: Uninitialized variable in malidp_se_check_scaling()
  drm/mali-dp: Align pitch size to be multiple of bus burst read size.
  drm/mali-dp: Rotated planes need a larger pitch size.
