Please observe the code around you. It may not have the best indentation style, but stick with what's there for all the other DPCD address definitions. > +#define DP_COLOR_RAMP (1 << 0) See how all the other address *content* definitions have a space between "#" and "define". I'm not saying I like it, but it's uniform in the file. While at it, why not add all of the defines for TEST_PATTERN. And observe how they are not bit patterns, so (1 << 0) should be just 1.
