From: Sonika Jindal <sonika.jindal@xxxxxxxxx>
Rename the defines to have levels instead of values for vswing and
pre-emph levels as the values may differ in other scenarios like low vswing of
eDP1.4 where the values are different.
Done using following cocci patch for each define:
@@
@@
# define DP_TRAIN_VOLTAGE_SWING_400 (0 << 0)
+ # define DP_TRAIN_VOLTAGE_SWING_LEVEL_0 (0 << 0)
