drm/msm/dp: reuse generic HDMI codec implementation

2025-05-02T00:54:03Z

The MSM DisplayPort driver implements several HDMI codec functions in the driver, e.g. it manually manages HDMI codec device registration, returning ELD and plugged_cb support. In order to reduce code duplication reuse drm_hdmi_audio_* helpers and drm_bridge_connector integration.

drm/msm/dp: prefix all symbols with msm_dp_

2024-10-31T19:08:01Z

For historical reasons a lot of symbols in the MSM DisplayPort driver used the generic dp_ prefix. Perform a mass-rename of those symbols to use msm_dp prefix. Basically this is a result of the following script: sed drivers/gpu/drm/msm/dp/* -i -e 's/\/\1/g' Yes, this also results in renaming of several struct fields in addition to renaming the structs and functions, but I think the simple solution is better than the more complex one.

drm/msm/dp: Remove unused defines and members

Throughout the Qualcomm Displayport driver a number of defines and struct members has become unused, but lingers in the code. Remove these.

drm/msm/dp: drop dp_parser

2024-02-11T20:38:07Z

Finally drop separate "parsing" submodule. There is no need in it anymore. All submodules handle DT properties directly rather than passing them via the separate structure pointer.

drm/msm/dp: rename is_connected with link_ready

2023-12-03T00:13:17Z

The is_connected flag is set to true after DP mainlink successfully finishes link training to enter into ST_MAINLINK_READY state rather than being set after the DP dongle is connected. Rename the is_connected flag with link_ready flag to match the state of DP driver's state machine.

drm/msm/dp: tie dp_display_irq_handler() with dp driver

2023-12-03T00:13:17Z

Currently the dp_display_request_irq() is executed at msm_dp_modeset_init() which ties irq registering to the DPU device's life cycle, while depending on resources that are released as the DP device is torn down. Move register DP driver irq handler to dp_display_probe() to have dp_display_irq_handler() IRQ tied with DP device. In addition, use platform_get_irq() to retrieve irq number from platform device directly.

drm/msm/dp: cleanup debugfs handling

2023-12-03T00:12:49Z

Currently there are two subdirs for DP debugfs files, e.g. DP-1, created by the drm core for the connector, and the msm_dp-DP-1, created by the DP driver itself. Merge those two, so that there are no extraneous connector-related subdirs.
