Subject: [PATCH v4 0/5] drm: fix two issues related to HDMI Connector
implementation
Running IGT tests on Qualcomm Dragonboard820c uncovered two issues with
the HDMI Connector implementation and with its integration into the
drm_bridge_connector. Fix those issues.
Note, I'm not fully satisfied with the drm_bridge_connector move. Maybe
it's better to add drm_bridge_funcs::connector_reset() and call it from
__drm_atomic_helper_connector_reset().
Depends on https://lore.kernel.org/dri-devel/20240704-panel-sw43408-fix-v6-1-3ea1c94bbb9b@linaro.org

Changes in v4:
- Fixed DRM_MODE_PROP_IMMUTABLE to use MUST in the single-value clause (Maxime)
- Rebased on top of DRM_DSC_HELPERS patch
- Removed 'depends on DRM_DISPLAY_HELPER' (Maxime)
- Link to v3: https://lore.kernel.org/r/20240702-drm-bridge-connector-fix-hdmi-reset-v3-0-12b0e3124ca4@linaro.org
Changes in v3:
- Document the DRM_MODE_PROP_IMMUTABLE requirements currently exposed
only via IGT tests (Maxime).
- Move drm_bridge_connector to drm_display_helper.
- Link to v2: https://lore.kernel.org/r/20240623-drm-bridge-connector-fix-hdmi-reset-v2-0-8590d44912ce@linaro.org
Changes in v2:
- Actually pass the flags to drm_property_create_range().
- Link to v1: https://lore.kernel.org/r/20240623-drm-bridge-connector-fix-hdmi-reset-v1-0-41e9894dcdec@linaro.org
