Could you add it to your 5.14 queue? It's not very urgent but it'd be nice to clean it up eventually. -Doug

As per Dmitry Baryshkov [1]: a) The 2nd "reg" should be 0x3c because "Offset 0x38 is USB3_DP_COM_REVISION_ID3 (not used by the current driver though)." b) The 3rd "reg" "is a serdes region and qmp_v3_dp_serdes_tbl contains registers 0x148 and 0x154." I think because the 3rd "reg" is a serdes region we should just use the same size as the 1st "reg"?
