This series adds support for MST AUX devices.
A more descriptive 'mstpath' attribute is also added to MST connector
devices. In addition, the DP aux device is made to be a child of the
corresponding connector's device where possible (*). This allows udev
rules to provide descriptive symlinks to the AUX devices.
(*) This can only be done on drivers that register their connector and
aux devices via drm_connector_register() and drm_dp_aux_register()
respectively. The connector also needs to be registered before the aux
device.
Leo Li (6):
drm/dp: Use non-cyclic idr
drm/dp-mst: Use connector kdev as aux device parent
drm/sysfs: Add mstpath attribute to connector devices
drm/amd/display: Use connector kdev as aux device parent
drm/bridge/analogix-anx78xx: Use connector kdev as aux device parent
drm/nouveau: Use connector kdev as aux device parent
Ville Syrjälä (1):
drm/dp_mst: Register AUX devices for MST ports
