-MIME-Version: 1.0

-commit a3ef3c2da675a8a564c8bea1a511cdd0a2a9aa49 upstream.
-
-Reading DPCD registers has side-effects in general. In particular
-accessing registers outside of the link training register range
-(0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) is explicitly
-forbidden by the DP v2.1 Standard, see
-
-3.6.5.1 DPTX AUX Transaction Handling Mandates
-3.6.7.4 128b/132b DP Link Layer LTTPR Link Training Mandates
-
-Based on my tests, accessing the DPCD_REV register during the link
-training of an UHBR TBT DP tunnel sink leads to link training failures.
-
-Solve the above by using the DP_LANE0_1_STATUS (0x202) register for the
-DPCD register access quirk.
