As the Table 3-4 in eDP v1.2 spec:
DPCD 0000Dh:
Bit 1 = FRAMING_CHANGE_CAPABLE
A setting of 1 indicates that this is an eDP device that
uses only Enhanced Framing, independently of the setting by
the source of ENHANCED_FRAME_EN
And as the Table 3-3 in eDP v1.4 spec:
DPCD 0000Dh:
Bit 1 = RESERVED for eDP
New to eDP v1.4.(Read all 0s)
