Sync objects are new toplevel drm object, that contain a
pointer to a fence. This fence can be updated via command
submission ioctls via drivers.
There is also a generic wait obj API modelled on the vulkan
wait API (with code modelled on some amdgpu code).
These objects can be converted to an opaque fd that can be
passes between processes.
v2: rename reference/unreference to put/get (Chris)
fix leaked reference (David Zhou)
drop mutex in favour of cmpxchg (Chris)
v3: cleanups from danvet, rebase on drm_fops rename
check fd_flags is 0 in ioctls.
v4: export find/free, change replace fence to take a
syncobj. In order to support lookup first, replace
later semantics which seem in the end to be cleaner.

unnecessary pipe relevnt fields and simplifies event handling.
- clean up and fix up sw-trigger relevant code
. This patch series moves TE relevant code from Panel and HDMI
to DECON driver to fix a race between interrupt handlers and
DECON disable, and to fix timeout issue at wait-for-vblank.
. It removes unnecessary flags and check code specific to Exynos driver.

Failing to do so meant that we got a resume() callback on first use of

omap_gem uses page alignment for buffer stride. The related calculations
are a bit off, though, as byte stride of 4096 gets aligned to 8192,
instead of 4096.
This patch changes the code to use DIV_ROUND_UP(), which fixes those
calculations and makes them more readable.

When rotating 90/270 + mirroring with YUV422, the end result will have

TILER rotation with YUV422 pixelformats does not work at the moment. All
other pixel formats work, because the pixelformat's pixel size is equal
to tiler unit size (e.g. XR24's pixel size is 32 bits, and the TILER
unit size that has to be used is 32 bits).
For YUV422 formats this is not the case, as the TILER unit size has to
be 32 bits, but the pixel size is 16 bits. The end result is OCP errors
and sync losts.
This patch adds the code to adjust the variables for YUV422 formats.
We could make the code more generic by passing around the pixel format,
rotation type, angle and the tiler unit size, which would allow us to do
calculations without special case for YUV422. However, this would make
the code more complex, and at least for now this is much more easier to
handle with these two special cases for YUV422.

At the moment the dispc driver uses a custom enum for rotation. Change
it to use the DRM's DRM_MODE_ROTATE_*.
Note that mirroring is at the moment handled as a separate boolean in

Note, DSS HW uses clockwise rotation, DRM counter-clockwise.

We have three rotation methods supported by the SoCs with DSS: DMA,
VRFB and TILER.
DMA rotation works in theory on all DSS platforms, but in practice it's
unusable due to the huge amount of memory bandwidth it uses, and has
never really been used.
VRFB is available on OMAP3, but is not supported by omapdrm, even though
we have some code for it in the dispc driver.
TILER is supported on OMAP4/OMAP5/DRA7/AM5 platforms, but has some
driver bugs.
To clean up the driver to help fixing the TILER issues, this patch drops
the DMA and VRFB rotation support, leaving only TILER rotation.
