Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.
To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.
v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.
v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.
This will also conflict with ongoing drmP.h cleanup by others I
expect.
v3: Rebase on top of atomic bochs.
v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
other places (all suggested from Laurent adopted unchanged).
- sort alphabetically
v5: Actually try to sort them, and while at it, sort all the ones I
touch.
v6: Rebase onto i915 changes.
v7: Rebase once more.

Prepare handling for atomic modeset CRTC events. Currently, using the
transition helpers, CRTC events do not exist, but once we switch to
proper atomic modeset, they have to be handled.
We queue an event for the next vblank in two places:
- armada_drm_crtc_atomic_flush() provided we aren't doing an
atomic modeset.
- armada_drm_crtc_commit() if we are committing a modeset.
This ensures that the event is sent at the correct time (after all
updates have been written to the hardware and after the following
vblank.)

For atomic modeset, we need to set the sync signal polarities from the

Remove the unused CRTC colourspace properties - userspace does not make

The overlay plane support updates asynchronously to the request, but the
drm_plane_helper_update() transitional helper waits for a vblank event
before releasing the framebuffer. Using the transitional helper would
make the call block, which would introduce a performance regression.

methods for the plane, but implement our own legacy update method
rather than the transitional helper.

page_flip requests happen asynchronously, so we can't wait on the

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle.
Since armada isn't atomic we'll use crtc->enabled and crtc->mode instead
of the stuff under crtc_state.
Once everyone agrees on how the clip rectangle gets set up we can
move the code into drm_atomic_helper_check_plane_state().

This series builds upon the set of fixes previously submitted to move
Armada DRM closer to atomic modeset. We're nowhere near yet, but this
series helps to get us closer by unifying some of the differences
between the primary and overlay planes.
New features added allows userspace to disable the primary plane if
overlay is full screen and there's nothing obscuring the colorkey -
this saves having to fetch an entire buffer containing nothing but
colorkey when displaying full screen video.

Implement primary plane update without having to go through a modeset
to achieve that; the hardware does not require such complexity. This
means we treat the primary plane as any other, allowing the format,
size, position and scaling to be updated via the normal plane ioctls.
This also allows us to seemlessly disable and re-enable the primary
plane when (eg) displaying full-frame video without any graphic
clipping the overlaid video - which saves wasting memory bandwidth
needlessly verifying that the colorkey is indeed filling the entire
primary plane.

Disable planes at the next blanking period rather than immediately.
In order to achieve this, we need to delay the clearing of dcrtc->plane

the overlay code.
