According to the DP specification, unless all the LANEx_CR_DONE bits are set, the transmitter must read the ADJUST_REQUEST_LANEx_x, increase the voltage swing according to the request, and update the TRAINING_LANEx_SET bytes to match the new voltage swing setting. Refer to the DP specification v1.1a, Section 3.5.1.3 Link Training. Signed-off-by: Jingoo Han Signed-off-by: Florian Tobias Schandinat --- Reading git-diff-tree failed
