Unlike DP 1.2 edid corruption test, DP 1.4 requires to calculate
real CRC value of the last edid data block, and write it back.
Current edid CRC calculates routine adds the last CRC byte,
and check if non-zero.
This behavior is not accurate; actually, we need to return
the actual CRC value when corruption is detected.
This commit changes this issue by returning the calculated CRC,
and initiate the required sequence.
Change since v7
- Fix for CI.CHECKPATCH
Change since v6
- Add return check
Change since v5
- Obtain real CRC value before dumping bad edid
Change since v4
- Fix for CI.CHECKPATCH
Change since v3
- Fix a minor typo.
Change since v2
- Rewrite checksum computation routine to avoid duplicated code.
- Rename to avoid confusion.
Change since v1
- Have separate routine for returning real CRC.

CEA 861.3 spec adds colorimetry data block for HDMI.
Parsing the block to get the colorimetry data from
panel.
This was posted by Uma Shankar at
https://patchwork.kernel.org/patch/10861327/
Modified by Abhinav Kumar:
- Use macros to distinguish the bit fields for clarity
Changes in v2:
- Use the drm_edid.h macros in drm_edid.c (Stephen Boyd)

Because between HDMI and DP have different colorspaces, it adds
drm_mode_create_dp_colorspace_property() function for creating of DP
colorspace property.
v3: Addressed review comments from Ville
- Add new colorimetry options for DP 1.4a spec.
- Separate set of colorimetry enum values for DP.
v4: Add additional comments to struct drm_prop_enum_list.
Polishing an enum string of struct drm_prop_enum_list
v5: Change definitions of DRM_MODE_COLORIMETRYs to follow HDMI prefix and
DP abbreviations.
Add missed variables on dp_colorspaces.
Fix typo. [Uma]
v6: Addressed review comments from Ilia and Ville
- Split drm_mode_create_colorspace_property() to DP and HDMI connector.
v7: Fix typo [Jani Saarinen]
Fix white space.
v8: Addressed review comments from Ville
- Drop colorimetries which have another way to distinguish or which
would not be used.
v9: Addressed review comments from Ville

As between HDMI and DP have different colorspaces, in order to distinguish
colorspace of DP and HDMI, it renames drm_mode_create_colorspace_property()
function to drm_mode_create_hdmi_colorspace_property() function for HDMI
connector.
In order to apply changed drm api, i915 driver has channged.

drm_self_refresh_helper_update_avg_times() was incorrectly accessing the
new incoming state after drm_atomic_helper_commit_hw_done(). But this
state might have already been superceeded by an !nonblock atomic update
resulting in dereferencing an already free'd crtc_state.
TODO I *think* this will more or less do the right thing.. althought I'm
not 100% sure if, for example, we enter psr in a nonblock commit, and
then leave psr in a !nonblock commit that overtakes the completion of
the nonblock commit. Not sure if this sort of scenario can happen in
practice. But not crashing is better than crashing, so I guess we
should either take this patch or rever the self-refresh helpers until
Sean can figure out a better solution.

Currently the self refresh idle timer is a const set by the crtc. This
is fine if the self refresh entry/exit times are well-known for all
panels used on that crtc. However panels and workloads can vary quite a
bit, and a timeout which works well for one doesn't work well for
another.
In the extreme, if the timeout is too short we could get in a situation
where the self refresh exits are taking so long we queue up a self refresh
entry before the exit commit is even finished.
This patch changes the idle timeout to a moving average of the entry
times + a moving average of exit times + the crtc constant.
This patch was tested on rockchip, with a kevin CrOS panel the idle
delay averages out to about ~235ms (35 entry + 100 exit + 100 const). On
the same board, the bob panel idle delay lands around ~340ms (90 entry
+ 150 exit + 100 const).
WRT the dedicated mutex in self_refresh_data, it would be nice if we
could rely on drm_crtc.mutex to protect the average times, but there are
a few reasons why a separate lock is a better choice:
- We can't rely on drm_crtc.mutex being held if we're doing a nonblocking
commit
- We can't grab drm_crtc.mutex since drm_modeset_lock() doesn't tell us
whether the lock was already held in the acquire context (it eats
-EALREADY), so we can't tell if we should drop it or not
- We don't need such a heavy-handed lock for what we're trying to do,
commit ordering doesn't matter, so a point-of-use lock will be less
contentious

enabling CRC generation may itself trigger a commit. Add notes about
this to the kerneldoc.

- Clarified that anything that would disable CRCs counts as a full

This patch adds a DRM ENUM property to the selected connectors.
This property is used for mentioning the protected content's type
from userspace to kernel HDCP authentication.
Type of the stream is decided by the protected content providers.
Type 0 content can be rendered on any HDCP protected display wires.
But Type 1 content can be rendered only on HDCP2.2 protected paths.
So when a userspace sets this property to Type 1 and starts the HDCP
enable, kernel will honour it only if HDCP2.2 authentication is through
for type 1. Else HDCP enable will be failed.
Pekka have completed the Weston DRM-backend review in
https://gitlab.freedesktop.org/wayland/weston/merge_requests/48
and the UAPI for HDCP 2.2 looks good.
The userspace is accepted in Weston.
