29 * Unless otherwise noted, all values are from the DP 1.1a spec. Note that
30 * DP and DPCD versions are independent. Differences from 1.0 are not noted,
31 * 1.0 devices basically don't exist in the wild.
32 *
33 * Abbreviations, in chronological order:
34 *
35 * eDP: Embedded DisplayPort version 1
36 * DPI: DisplayPort Interoperability Guideline v1.1a
37 * 1.2: DisplayPort 1.2
38 * MST: Multistream Transport - part of DP 1.2a
39 *
40 * 1.2 formally includes both eDP and DPI definitions.
