[PATCH 2/7] drm/i915: Renaming DP training vswing pre emph defines

sonika.jindal
2014-08-08T10:53:41Z

From: Sonika Jindal <sonika.jindal@intel.com>

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)
