e4fa8457b2 drm/prime: Align gem_prime_export with obj_funcs.export
The idea is that gem_prime_export is deprecated in favor of
obj_funcs.export. That's much easier to do if both have matching
function signatures.

0424fdaf88 drm/prime: Actually remove DRIVER_PRIME everywhere
Split out to make the functional changes stick out more.

All places where DRIVER_PRIME was used have been removed in previous
patches already.

v2: amdgpu gained DRIVER_SYNCOBJ_TIMELINE.

v3: amdgpu lost DRIVER_SYNCOBJ_TIMELINE.

v4: Don't add a space in i915_drv.c (Sam)

v5: Add note that previous patches removed all the DRIVER_PRIME users
already (Emil).

v6: Fixupe ingenic (new driver) while applying.

drm: Remove users of drm_format_num_planes
drm_format_num_planes() is basically a lookup in the drm_format_info table
plus an access to the num_planes field of the appropriate entry.

Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to drm_format_num_planes is therefore more efficient.

Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.

fcd70cd36b drm: Split out drm_probe_helper.h
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.

96d4f267e4 Remove 'type' argument from access_ok() function
Nobody has actually used the type (VERIFY_READ vs VERIFY_WRITE) argument
of the user address range verification function since we got rid of the
old racy i386-only code to walk page tables by hand.

It existed because the original 80386 would not honor the write protect
bit when in kernel mode, so you had to do COW by hand before doing any
user access.  But we haven't supported that in a long time, and these
days the 'type' argument is a purely historical artifact.

A discussion about extending 'user_access_begin()' to do the range
checking resulted this patch, because there is no way we're going to
move the old VERIFY_xyz interface to that model.  And it's best done at
the end of the merge window when I've done most of my merges, so let's
just get this done once and for all.

This patch was mostly done with a sed-script, with manual fix-ups for
the cases that weren't of the trivial 'access_ok(VERIFY_xyz' form.

There were a couple of notable cases:

 - csky still had the old "verify_area()" name as an alias.

 - the iter_iov code had magical hardcoded knowledge of the actual
   values of VERIFY_{READ,WRITE} (not that they mattered, since nothing
   really used it)

 - microblaze used the type argument for a debug printout

but other than those oddities this should be a total no-op patch.

I tried to fix up all architectures, did fairly extensive grepping for
access_ok() uses, and the changes are trivial, but I may have missed
something.  Any missed conversion should be trivially fixable, though.

72fdb40c1a drm: extract drm_atomic_uapi.c
This leaves all the commit/check and state handling in drm_atomic.c,
while pulling all the uapi glue and the huge ioctl itself into a
seprate file.

This seems to almost perfectly split the rather big drm_atomic.c file
into 2 equal sizes.

Also adjust the kerneldoc and type a very terse overview text.

v2: Rebase.

v3: Fix tiny typo.

v4:
- Fixup armada, newly converted atomic driver hooray!
- Fixup msm/dpu1, newly added too.

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.)

bcd21a4786 Merge branch 'drm-armada-devel-4.15' of git://git.armlinux.org.uk/~rmk/linux-arm into drm-next
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.

950bc137c3 drm/armada: implement primary plane update
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.

890ca8df5a drm/armada: disable planes at next blanking period
Disable planes at the next blanking period rather than immediately.
In order to achieve this, we need to delay the clearing of dcrtc->plane
until after the next blanking period, so move that into a separate
work function.  To avoid races, we also need to move its assignment in
the overlay code.

7bfab1ec45 drm/armada: use drm_plane_helper_check_state()
Use drm_plane_helper_check_state() to check the overlay plane state
rather than drm_plane_helper_check_update(), as:

(1) using drm_plane_helper_check_state() provides a better migration
    path to atomic modeset
(2) it avoids needless copies of drm rectangle structures, and so is
    more efficient.

Move the overlay plane work out from under the spinlock so that both the

However, we must update the CRTC registers under the spinlock, so fix up
