This tool serves as a wrapper around the constructs provided by the drm_dpcd_aux_dev kernel module by working on the /dev/drm_dp_aux[n] devices created by the kernel module. It supports reading and writing dpcd registers on the connected aux channels. In the follow-up patch, support for decoding these registers will be added to facilate debugging panel related issues. v2: (Fixes by Rodrigo but no functional changes yet): - Indentations, Typo, Missed spaces - Removing mentioning to decode and spec that is not implemented yet. - Add Makefile.sources back - Missed s/printf/igt_warn v3: - Address DK's review comments from v2 above. - Squash Rodrigo's file handling unification patch. - Make count, offset and device id optional. v4: - Better error handling and refactoring.
