[PATCH 00/13] drm/msm/dp: Add static HDR support for DP and eDP

[Xilin Wu]

This series adds standard KMS static HDR metadata and BT.2020 RGB
signalling to MSM DP and eDP, with HDR10 as the intended use case. It uses
HDR_OUTPUT_METADATA, Colorspace and max bpc. Userspace supplies the HDR
pixel content; DSC, dynamic HDR and tone mapping are outside this series.

Patch 1 allows max bpc registration before connector state allocation and
initializes the corresponding state defaults. Patch 2 prepares generic
SDP slots. Patches 3-5 establish PHY power ownership, serialize HPD state
updates and add complete stream enable rollback, including AUX recovery
for a connected external peer. New error returns are introduced together
with their cleanup paths.

Patches 6-8 add deferred link-status notification, capability cache
validity and stream reconstruction for modesets leaving eDP self refresh.
Patches 9-10 add atomic output depth selection and BT.2020 RGB signalling.
The BT.2020 patch includes its own PSR disable/restore handling.

Patch 11 independently fixes the uninitialized debugfs connector pointer.
Patch 12 serializes SDR video-test state changes with mode programming.
Patch 13 adds complete static HDR support: metadata validation and packing,
10 bpc enforcement, Generic2 programming and teardown, stream restoration,
PSR exclusion and arbitration with video-pattern tests. A test request
arriving after atomic check cannot replace the checked HDR output depth.

This series is tested on a Lenovo Yoga Slim 7x using x1e80100.
