This fixes a problem found on the MacBookPro 2017 Retina panel.
The panel reports 10 bpc color depth in its EDID, and the
firmware chooses link settings at boot which support enough
bandwidth for 10 bpc (324000 kbit/sec = multiplier 0xc),
but the DP_MAX_LINK_RATE dpcd register only reports
2.7 Gbps (multiplier value 0xa) as possible, in direct
contradiction of what the firmware successfully set up.
This restricts the panel to 8 bpc, not providing the full
color depth of the panel.
This patch adds a quirk specific to the MBP 2017 15" Retina
panel to add the additiional 324000 kbps link rate during
edp setup.
Link to previous discussion of a different attempted fix
with Ville and Jani:
https://patchwork.kernel.org/patch/11325935/
v2: Follow Jani's proposal of defining quirk_rates[] instead
of just appending 324000. This for better clarity.
v3: Rebased onto current drm-tip, as of 16-March-2020. Adapt
to new edid_quirks parameter of drm_dp_has_quirk().

drm_mode_config_init() may not have been called when the driver/device
doesn't support modeset. That will cause drm_mode_config_validate()
to oops. Skip the validation for !modeset.
TODO: We may want to consider calling drm_mode_config_init()
unconditionally to avoid similar issues elsewhere...

As a result of commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail) and changes to various debugfs
functions in drm/core and across various drivers, there is no need for
the drm_driver.debugfs_init() hook to have a return value. Therefore,
declare it as void.
This also includes refactoring all users of the .debugfs_init() hook to
return void across the subsystem.
v2: include changes to the hook and drivers that use it in one patch to
prevent driver breakage and enable individual successful compilation of
this change.

Many drivers are populating encoder->possible_clones wrong. Let's
persuade them to get it right by adding some loud WARNs.
We'll cross check the bits between any two encoders. So either
both encoders can clone with the other, or neither can.
We'll also complain about effectively empty possible_clones, and
possible_clones containing bits for encoders that don't exist.

I doubt the DP+DP and SDVO+SDVO cloning works for this driver.
i915 at least doesn't do those. Truthfully there could be some very
specific circumstances where some of them would do doable, but
genereally it's too much pain to deal with so we've chose not to
bother. Let's use the same approach for gma500.
Also the LVDS+LVDS and DSI+DSI cases probably don't really exist as
there is one of each at most.
This does mean we'll now leave possible_clones at 0 for these encoder
types whereas previosuly we included the encoder itself in the bitmask.
But that's fine as the core now treaks 0 as a special case and adds
the encoder itself into the final bitmask reported to userspace.

The docs say possible_clones should always include the encoder itself.
Since most drivers don't want to deal with the complexities of cloning
let's allow them to set possible_clones=0 and instead we'll fix that
up in the core.
We can't put this special case into drm_encoder_init() because drivers
will have to fill up possible_clones after adding all the relevant
encoders. Otherwise they wouldn't know the proper encoder indexes to
use. So we'll just do it just before registering the device.
v2: Don't set the bit if possible_clones!=0 so that the
validation (coming soon) will WARN (Thomas)
Fix up the docs to allow possible_clones==0 (Daniel)

Currently the DispID tile block gets parsed in drm_get_edid(), which
is an odd place for it considering we parse nothing else there. Also
this doesn't work for override EDIDs since
drm_connector_update_edid_property() refuses to do its job twice
in such cases. Thus we never update the tile property with results
of the DispID tile block parsing during drm_get_edid().
To fix this let's just move the tile block parsing to happen during
drm_connector_update_edid_property(), which is where we parse a bunch
of other stuff as well (and where we update both the EDID and tile
properties).

Currently the code assumes that the entire EDID extesion block
can be taken up by the DispID blocks. That is not true. There
is at least always the DispID checksum, and potentially fill
bytes if the extension block uses the interior fill scheme
to pad out to fill EDID block size.
So let's not parse the checksum or the fill bytes as DispID
blocks by having drm_find_displayid_extension() return the
actual length of the DispID data to the caller.

The fact that the DispID starts at byte offset 1 is due to
the DispID coming from and EDID extension block (the first byte
being the extesion block tag). Instead of hadrdocoding that idx==1
assumptions all over let's just have drm_find_displayid_extension()
return it since it actually knows what it's talking about.
If at some point someone comes across a DispID which is not embedded
inside an EDID the function that returns the new type of DispID
can return it's own byte offset without having to updated all the
code.

and just return the thing we want directly.

Since commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail), drm_debugfs_create_files() never
fails and should return void. Therefore, remove its use as the
return value of arcpgu_debugfs_init() and have the latter function return
0 directly.
v2: convert the function to return 0 instead of void to avoid breaking
the build and ensure that this individual patch compiles properly.

by drm_master_put.
drm_master_put
->drm_master_destroy
->idr_destroy
So we needn't call idr_destroy again.

For icl+, have hw read out to create hw blob of gamma
lut values. icl+ platforms supports multi segmented gamma
mode by default, add hw lut creation for this mode.
This will be used to validate gamma programming using dsb
(display state buffer) which is a tgl specific feature.
v2: -readout code for multisegmented gamma has to come
up with some intermediate entries that aren't preserved
in hardware (Jani N)
-linear interpolation (Ville)
-moved common code to check gamma_enable to specific funcs,
since icl doesn't support that
v3: -use u16 instead of __u16 [Jani N]
-used single lut [Jani N]
-improved and more readable for loops [Jani N]
-read values directly to actual locations and then fill gaps [Jani N]
-moved cleaning to patch 1 [Jani N]
-renamed icl_read_lut_multi_seg() to icl_read_lut_multi_segment to
make it similar to icl_load_luts()
-renamed icl_compute_interpolated_gamma_blob() to
icl_compute_interpolated_gamma_lut_values() more sensible, I guess
v4: -removed interpolated func for creating gamma lut values
-removed readouts of fine and coarse segments, failure to read PAL_PREC_DATA
correctly
v5: -added gamma_enable check inside read_luts()
v6: -renamed intel_color_lut_entry_equal() to intel_color_lut_entries_equal() [Ville]
-changed if-else to switch [Ville]
-removed intel_color_lut_entry_multi_equal() [Ville]
v7: -checkpatch warnings
v8: -rebased
v9: -rebased, aligned with Ville's style of gamma cleanup

It is an unlike condition, it make sense to remove this condition.

The new struct contains afbc-specific data.
The new function can be used by drivers which support afbc to complete
the preparation of struct drm_afbc_framebuffer. It must be called after
allocating the said struct and calling drm_gem_fb_init_with_funcs().

Allow allocating a specialized version of struct drm_framebuffer
by moving the actual fb allocation out of drm_gem_fb_create_with_funcs();
the respective functions names are adjusted to reflect that fact.
Please note, though, that standard size checks are performed on buffers,
so the drm_gem_fb_init_with_funcs() is useful for cases where those
standard size checks are appropriate or at least don't conflict the
checks to be performed in the specialized case.
Thanks to this change the drivers can call drm_gem_fb_init_with_funcs()
having allocated their special version of struct drm_framebuffer, exactly
the way the new version of drm_gem_fb_create_with_funcs() does.

The function name mentioned in the documentational comments mismatches
the actual one. The mismatch may make trouble for automatic documentation
generation. One of the erronous name has seen to be misused
and fixed in commit bc5ab2d29b8a ("drm/amdgpu: fix typo in function
sdma_v4_0_page_resume").
There is apparently no functional change in the patch.
