The DisplayPort 1.4 RX Subsystem supports
the following eDP features:
- Reduced Aux timing because the Aux sync pattern is reduced from 8 pulses to 16 pulses.
- Alternate Scrambler Seed Reset (ASSR)
- Enhanced Framing
- Fast link training
- Black video
- Backlight control by way of Aux
eDP can be enabled by using the following Tcl command:
set_property -dict [list CONFIG.EDP_ENABLE {true}] [get_bd_cells v_dp_rxss1_0]When generating the subsystem, if EDP_ENABLE is set to true, in the
Version register (Offset 0x0F8) Bits [7:0]-Internal Revision is updated
with 0x01.
Note: The eDP feature uses the same
hardware infrastructure (connector, FMC/PCB, pinouts) of the regular DisplayPort
1.4.
