drm/msm: make it possible to disable KMS-related code.

2025-07-05T14:13:35+00:00

If the Adreno device is used in a headless mode, there is no need to build all KMS components. Build corresponding parts conditionally, only selecting them if modeset support is actually required.

drm/msm/dp: drop the msm_dp_catalog module

2025-07-04T13:35:19+00:00

Now as the msm_dp_catalog module became nearly empty, drop it, accessing registers directly from the corresponding submodules.

drm/msm/dp: prefix all symbols with msm_dp_

2024-10-31T19:08:01+00:00

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: Drop unused dp_debug struct

2024-04-22T13:22:49+00:00

The members of struct dp_debug are no longer used, so the only purpose of this struct is as a type of the return value of dp_debug_get(), to signal success/error. Drop the struct in favor of signalling the result of initialization using an int, then merge dp_debug_get() with dp_debug_init() to avoid the unnecessar boilerplate code.

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: cleanup debugfs handling

2023-12-03T00:12:49+00:00

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.
