2024-04-22drm/msm/dp: Drop unused dp_debug structBjorn Andersson1-27/+11
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.

2023-12-03drm/msm/dp: cleanup debugfs handlingDmitry Baryshkov1-16/+7
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.

2023-06-04drm/msm/dp: remove most of usbpd-related remainsDmitry Baryshkov1-3/+2
Remove most of remains of downstream usbpd code. Mainline kernel uses different approach for managing Type-C / USB-PD, so this remains unused.

2021-10-15drm/msm/dp: Use the connector passed to dp_debug_get()Bjorn Andersson1-2/+2
The debugfs code is provided an array of a single drm_connector. Then to access the connector, the list of all connectors of the DRM device is traversed and all non-DisplayPort connectors are skipped, to find the one and only DisplayPort connector. But as we move to support multiple DisplayPort controllers this will now find multiple connectors and has no way to distinguish them. Pass the single connector to dp_debug_get() and use this in the debugfs functions instead, both to simplify the code and the support the multiple instances.
