Could this perhaps be simply:
#define DP_TRAIN_VOLTAGE_SWING(x) ((x) << 0)
As it is, there's no information about the value within the symbolic
name anyway, so _LEVEL_* really isn't that useful and keeping several
macros for each value seems isn't either.
An alternative would be to provide a second set of defines for eDP 1.4
where the name implies the meaning and then use them as appropriate.
