This series updates DPCD 248h register name and PHY test patterns names to follow DP 2.0 Specs.
Also updates the DP PHY CTS codes of the affected drivers (i915, amd, msm)
No functional changes expected.

You can't do renames like this piece by piece. Every commit must build.

Incidentally, this is one of the reasons we often don't bother with
renames to follow spec changes, but rather stick to the original names.

However, in this case you could switch all drivers to the different test
pattern macros piece by piece, as they're already there.


BR,
Jani.

Noted, I apologize for messing that up.
 
I will send v2 to make sure all renames of DP_PHY_TEST_PATTERN
done in one patch with the other changes you requested.

Thank you for your review
