eDP_TX[3:0]
eDP_TX#[3:0]
Embedded DisplayPort Transmit Differential
Pair: Nominally, eDP_TX[3:0] is multiplexed
with PEG_TX[12:15] and eDP_TX#[3:0] is
multiplexed with PEG_TX#[12:15]. When
reversed, eDP_TX[3:0] is multiplexed with
PEG_TX[3:0] and eDP_TX#[3:0] is multiplexed
with PEG_TX#[3:0]

eDP_AUX
eDP_AUX#
Embedded DisplayPort Auxiliary Differential
Pair: Nominally, eDP_AUX is multiplexed with
PEG_RX[13] and eDP_AUX# is multiplexed
with PEG_RX#[13]. When reversed, eDP_AUX
is multiplexed with PEG_RX[2] and eDP_AUX#
is multiplexed with PEG_RX#[2]
