Yes Jani I did notice the same thing and didnt know which convention
to continue to follow but I noticed that majority of the defines were
just EDID_ so just used that for these new defines.

Is there a particular way you wish to consolidate this and use a specific
convention for #defines?

I can atleast change these new defines based on a preferred convention and then
separate patches to change the rest in .h and corresponding usages in .c files.
