<drm/drm_crtc.h> used to define most of the in-kernel KMS API. It has
now been split into separate files for each object type, but still
includes most other KMS headers to avoid breaking driver compilation.
As a step towards fixing that problem, remove the inclusion of
<drm/drm_encoder.h> from <drm/drm_crtc.h> and include it instead where
appropriate. Also remove the forward declarations of the drm_encoder and
drm_encoder_helper_funcs structures from <drm/drm_crtc.h> as they're not
needed in the header.
<drm/drm_encoder.h> now has to include <drm/drm_mode.h> and contain a
forward declaration of struct drm_encoder in order to allow including it
as the first header in a compilation unit.

Big thing is that drm-misc is now officially a group maintainer/committer
model thing, with MAINTAINERS suitably updated. Otherwise just the usual
pile of misc things all over, nothing that stands out this time around.

drm: move allocation out of drm_get_format_name()
to be able to apply his patches without conflicts.
Signed-off-by: Daniel Vetter <daniel.vetter@intel.com>
Currently, if drm.debug is enabled, we get a DRM_ERROR message on the
intermediate edid reads. This causes transient failures in CI which
flags up the sporadic EDID read failures, which are recovered by
rereading the EDID automatically. This patch combines the reporting done
by drm_do_get_edid() itself with the bad block printing from
get_edid_block(), into a single warning associated with the connector
once all attempts to retrieve the EDID fail.
v2: Print the whole EDID, marking up the bad/zero blocks. This requires
recording the whole of the raw edid, then a second pass to reduce it to
the valid extensions.
v3: Fix invalid/valid extension fumble.

We seem to have a bit a mess in how to describe the bus formats, with
a multitude of competing ways. Might be best to consolidate it all and
use MEDIA_BUS_FMT_ also for the hdmi color formats and high color
modes.
Also move all the display_info related functions into drm_connector.c
(there's only one) to group it all together. I did decided against
also moving the edid related display info functions, they seem to fit
better in drm_edid.c. Instead sprinkle a few cross references around.
While at that reduce the kerneldoc for static functions, there's not
point in documenting internals with that much detail really.
v2: Fix typo and move misplaced hunk (Sean).

According to E-EDID spec 1.3, table 3.9, a digital video sink with the
"DFP 1.x compliant TMDS" bit set is "signal compatible with VESA DFP 1.x
TMDS CRGB, 1 pixel / clock, up to 8 bits / color MSB aligned".
For such displays, the DFP spec 1.0, section 3.10 "EDID support" says:
"If the DFP monitor only supports EDID 1.X (1.1, 1.2, etc.)
without extensions, the host will make the following assumptions:
1. 24-bit MSB-aligned RGB TFT
2. DE polarity is active high
3. H and V syncs are active high
4. Established CRT timings will be used
5. Dithering will not be enabled on the host"
So if we don't know the bit depth of the display from additional
colorimetry info we should assume 8 bpc / 24 bpp by default.
This patch adds info->bpc = 8 assignement for that case.

Bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=105331
reports that the "AEO model 0" display is driven with 8 bpc
without dithering by default, which looks bad because that
panel is apparently a 6 bpc DP panel with faulty EDID.
A fix for this was made by commit 013dd9e038
("drm/i915/dp: fall back to 18 bpp when sink capability is unknown").
That commit triggers new regressions in precision for DP->DVI and
DP->VGA displays. A patch is out to revert that commit, but it will
revert video output for the AEO model 0 panel to 8 bpc without
dithering.
The EDID 1.3 of that panel, as decoded from the xrandr output
attached to that bugzilla bug report, is somewhat faulty, and beyond
other problems also sets the "DFP 1.x compliant TMDS" bit, which
according to DFP spec means to drive the panel with 8 bpc and
no dithering in absence of other colorimetry information.
Try to make the original bug reporter happy despite the
faulty EDID by adding a quirk to mark that panel as 6 bpc,
so 6 bpc output with dithering creates a nice picture.
Tested by injecting the edid from the fdo bug into a DP connector
via drm_kms_helper.edid_firmware and verifying the 6 bpc + dithering
is selected.
This patch should be backported to stable.

The tiled 5K Dell monitor appears to be hiding it's tiled mode
inside the displayid timings block, this patch parses this
blocks and adds the modes to the modelist.
