[PATCH v9 0/3] Add drm_dp_aux chardev support.

[Rafael Antognolli]

This series implement support to a drm_dp_aux chardev that allows reading and
writing an arbitrary amount of bytes to arbitrary dpcd register addresses using
regular read, write and lseek operations.

Rafael Antognolli (3):
  drm/kms_helper: Add a common place to call init and exit functions.
  drm/dp: Add a drm_aux-dev module for reading/writing dpcd registers.
  drm/dp: Set aux.dev to the drm_connector device, instead of
    drm_device.
