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.

The drm_writeback_queue_job() function takes ownership of the passed job
and requires the caller to manually set the connector state
writeback_job pointer to NULL. To simplify drivers and avoid errors
(such as the missing NULL set in the vc4 driver), pass the connector
state pointer to the function instead of the job pointer, and set the
writeback_job pointer to NULL internally.

In malidp, the writeback pipeline does not support writing crtc output
to a framebuffer with modifiers ie the memory writeback content is
devoid of any compression or tiling, etc.
So we have added a commit check in memory writeback encoder helper function
to validate if the framebuffer has any modifier and if so, return EINVAL.

We need to define a common list of format modifiers supported by each of
the Mali display processors.
The following are the constraints with AFBC:-
1. AFBC is not supported for the formats defined in
malidp_hw_format_is_linear_only()
2. Some of the formats are supported only with AFBC modifiers. Thus we have
introduced a new function 'malidp_hw_format_is_afbc_only()' which verifies
the same.
3. AFBC_FORMAT_MOD_YTR needs to be provided for any RGB format.
4. Formats <= 16bpp cannot support AFBC_FORMAT_MOD_SPLIT.
5. CBR should not be set for non-subsampled formats.
6. SMART layer does not support framebuffer with AFBC modifiers.
Return -EINVAL for such a scenario.
7. AFBC_FORMAT_MOD_YTR is not supported for any YUV formats.
8. Formats which are subsampled cannot support AFBC_FORMAT_MOD_SPLIT.
However in DP550, YUV_420_10BIT is supported with AFBC_FORMAT_MOD_SPLIT.
This feature has been identified with
MALIDP_DEVICE_AFBC_YUV_420_10_SUPPORT_SPLIT.
9. In DP550 and DP650, for YUYV, the hardware supports different
format-ids to be used with and without AFBC modifier. We have used the
feature 'MALIDP_DEVICE_AFBC_YUYV_USE_422_P2' to identify this
characteristic.
10. DP500 does not support split mode (ie AFBC_FORMAT_MOD_SPLIT). We have
used the feature 'MALIDP_DEVICE_AFBC_SUPPORT_SPLIT' to identify the DPs
which support SPLIT mode.
11. DP550 supports YUV420 with split mode. We have defined the feature
'AFBC_SUPPORT_SPLIT_WITH_YUV_420_10' to identify this characteristic.
Changes since v1:-

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.

When we want to writeback to memory in NV12 format we need to program
the RGB2YUV coefficients. Currently, we don't program the coefficients
and NV12 doesn't work at all.
This patchset fixes that by programming a sane default(bt709, limited
range) as rgb2yuv coefficients.
In the long run, probably we need to think of a way for userspace to
be able to program that, but for now I think this is better than not
working at all or not advertising NV12 as a supported format for
memwrite.
Changes since v1:
- Write the rgb2yuv coefficients only once, since we don't change
them at all, just write them the first time NV12 is programmed,
suggested by Brian Starkey, here [1]

Older version of this patch series reported writeback as disconnected
to avoid confusing userspace not aware of writeback connectors.
However, the version that got merged uses a special cap
(DRM_CLIENT_CAP_WRITEBACK_CONNECTORS) for this purpose.
This helps us avoid some special handling of writeback connector
in drm_helper_probe_single_connector_modes, see [1].
