[PATCH 0/7] Add DP MST AUX devices

[sunpeng.li at amd.com]

From: Leo Li <sunpeng.li at amd.com>

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

  drm/dp_mst: Register AUX devices for MST ports
