55cdb31449 Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
This is a last pull request, which includes two g2d patches
   I missed, and more cleanup series of Exynos drm driver.

   The cleanup series makes Exynos drm driver more simple,
   and removes unnecessary codes, and considers multiple plane format
   of framebuffer. I hope this not to be late.

c3058579a2 drm/exynos: remove buf_cnt from struct exynos_drm_fb
Looking other drm drivers, there is no the restriction that framebuffer
has only one buffer in .create_handle() callback. They use just first
buffer.

If this limitation is removed, there is no reason keeping buffer count
for framebuffer, so we can remove buf_cnt from struct exynos_drm_fb.

The size check was incomplete. It only computed the
size of area of the drawing rectangle and checked if
the size still fit inside the buffer.

The correct check is to compute the position of the
last byte that the G2D engine is going to access and
then check if that position is still contained in the
buffer. In particular we need the stride information
to determine this.

implemented by the drivers. If drm core requests an async commit
exynos_atomic_commit() will now schedule a work task to run the update later.

It also serializes commits that needs to run on the same crtc, putting the
following commit to wait until the current one is finished.

cb11b3f189 drm/exynos: fimd: only finish update if START == START_S
fimd_update_plane() programs BUF_START[win] and during the update
BUF_START[win] is copied to BUF_START_S[win] (its shadow register)
and starts scanning out, then it raises a irq.

The fimd_irq_handler, in the case we have a pending_fb, will check
the fb value was copied to START_S register and finish the update
in case of success.

Based on patch from Daniel Kurtz <djkurtz@chromium.org>

822f6dfd71 drm/exynos: check for pending fb before finish update
The current code was ignoring the end of update for all overlay planes,
caring only for the primary plane update in case of pageflip.

This change adds a change to start to check for pending updates for all
planes through exynos_plane->pending_fb. At the start of plane update the
pending_fb is set with the fb to be shown on the screen. Then only when to
fb is already presented in the screen we set pending_fb to NULL to
signal that the update was finished.

d9220d4733 drm/exynos: add prepare and cleanup phases for planes
From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>

.prepare_plane() and .cleanup_plane() allows to perform extra operations
before and after the update of planes. For FIMD for example this will
be used to enable disable the shadow protection bit.

struct drm_crtc already stores the enabled state of the crtc
thus we don't need to replicate enabled in exynos_drm_crtc.
