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 (2): 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.
