[RFC PATCH 4/4] drm/msm/dp: Use DPCD 248h DP 2.0 new names/definitions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use DP 2.0 DPCD 248h new name (LINK_QUAL_PATTERN_SELECT) and rename selected phy test patterns to LINK_QUAL_PATTERN_*

Note: TPS4 LT pattern is CP2520 Pattern 3 (refer to DP2.0 spaces Table 3-11, DPCD 00248h
LINK_QUAL_PATTERN_SELECT, and DP PHY 1.4 CTS - Appendix A - Compliance EYE Pattern(CP2520; Normative))
That is why the change from DP_PHY_TEST_PATTERN_SEL_MASK to DP_LINK_QUAL_PATTERN_CP2520_PAT_3
No functional changes
