Adding new defines, older one will be removed in the last patch in the series.
This is to 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)
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.
I feel _LEVEL_* makes it more readable and since there are only 4 values
possible, it is ok to have 4 different macros for readability purpose.
What do you think?
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.
