The A23's display pipeline is similar to the A33. Differences include:
- Display backend supports larger layers, 8192x8192 instead of 2048x2048
- TCON has DMA input
- There is no SAT module packed in the display backend
Add support for the display pipeline and its components.
As the MIPI DSI output device is not officially documented, and there
are no A23 reference devices to test it, it is not covered by this
patch.

In some cases, such as running a new kernel with an old device tree that
has the frontend disabled, the backend's matching frontend might be
unavailable.
When this happens, the layers should only declare support for formats
that the backend support. This partially reverts commit 1c29d263f6
("drm/sun4i: Rename sun4i_backend_layer_formats to sun4i_layer_formats")
by bringing back sun4i_backend_layer_formats, and passing it to
drm_universal_plane_init, while also dropping the modifiers list,
in the event no frontend is available.

The table has been unified across OSes to minimize virtualization overhead.
The MOCS table is now published as part of bspec, and versioned. Entries
are supposed to never be modified, but new ones can be added. Adding
entries increases table version. The patch includes version 1 entries.
Meaning of each entry is now explained in bspec, and user mode clients
are expected to know what each entry means. The 3 entries used for previous
platforms are still compatible with their legacy definitions, but that is
not guaranteed to be true for future platforms.
v2: Fixed SCC values, improved commit comment (Daniele)
v3: Improved MOCS table comment (Daniele)
v4: Moved new entries below gen9 ones. Put common entries into

Make the defines for LE and L3 caching options to contain the shifts and
remove the zeros from the tables as shifting zeros always result in
zero.
Starting from Ice Lake the MOCS table is defined in the spec and
contains all entries. So to simplify checking the table with the values
set in code, the value is now part of the macro name. This allows to
still give the most used option and sensible name, but also to easily
cross check the table from the spec for gen >= 11.
By removing the zeros we avoid maintaining a huge table since the one
from spec contains many more entries. The new table for Ice Lake will
be added by other patches, this only reformats the table.
While at it also fix the indentation.

From Chris: "What it does mean is that the buffer contents are consistent

The bindings for Qualcomm opp levels changed after being Acked but
before landing. Thus the code in the GPU driver that was relying on
the old bindings is now broken.
Let's change the code to match the new bindings by adjusting the old
string 'qcom,level' to the new string 'opp-level'. See the patch
("dt-bindings: opp: Introduce opp-level bindings").
NOTE: we will do additional cleanup to totally remove the string from
the code and use the new dev_pm_opp_get_level() but we'll do it in a
future patch. This will facilitate getting the important code fix in
sooner without having to deal with cross-maintainer dependencies.
This patch needs to land before the patch ("arm64: dts: sdm845: Add

Now that our state comparison functions are pretty complete, we should
enable fastset by default when a modeset can be avoided. Even if we're
not completely certain about the inherited state, we can be certain
after the first modeset that our sw state matches the hw state.
There is one testcase explicitly testing fastset,
kms_panel_fitting.atomic-fastset but other testcases do so indirectly
because most tests don't clean up the display during exit, or otherwise
indirectly preserve mode by doing igt_display_reset or inheriting during
init.

We currently program userspace-provided gamma and degamma LUT's into our
hardware without really checking to see whether they satisfy our
hardware's rules. We should try to catch tables that are invalid for
our hardware early and reject the atomic transaction.
All of our platforms that accept a degamma LUT expect that the entries
in the LUT are always flat or increasing, never decreasing. Also, our
GLK and ICL platforms only accept degamma tables with r=g=b entries; so
we should also add the relevant checks for that in anticipation of
degamma support landing for those platforms.
v2:
- Use new API (single check function with bitmask of tests to apply)
- Call helper for our gamma table as well (with no additional tests
specified) so that the table size will be validated.
v3:
- Don't call on the gamma table since the LUT size is already tested at
property blob upload and we don't have any additional hardware
constraints for that LUT.
v4:
- Apply equal color channel check on gen10 as well; the bspec has some
strange tagging for CNL platforms, but this appears to apply there as
well. (Ville)
