[PATCH 0/4] drm/bridge-connector: simplify handling of USB-C DP

From: Dmitry Baryshkov
Date: Fri Jul 28 2023 - 20:50:52 EST


During the discussion of DP connetors, it was pointed out that existing
DP drivers supporting USB-C altmode (AMDGPU, Intel) use
DRM_MODE_CONNECTOR_DisplayPort for such connectors rather than
DRM_MODE_CONNECTOR_USB.

This patchset attempts to solve this issue. It adds USB to the enum
drm_dp_subconnector and then provides a simple yet efficient way to
define DP-in-USB subconnector type for the drivers that use
drm_bridge_connector.

Dmitry Baryshkov (4):
drm: allow specifying default subtype for the DP subconnector property
drm/bridge-connector: handle subconnector types
drm/uapi: document the USB subconnector type
soc: qcom: pmic_glink: properly describe the DP connector
