struct

If true, data is swapped on the lanes output by the port.

This field must not be changed while the DDI is enabled.

Tiger Lake and DG1:

FIA handles lane reversal for Thunderbolt and USB-C DisplayPort Alt Mode,

and this field should be set to false in those cases. Static and fixed

connections (DisplayPort, HDMI) through the FIA only use this field in

"No pin Assignment (Non Type-C DP)" static configurations. Other

connections use the field.

Kaby Lake and Skylake:

For DDIs B-D, enabling swaps lanes 0

<

-> 3 and lanes 1

<

-> 2. If DDI E is

enabled (in DDI A Lane Capability Control), then DDI A reversal swaps its

two remaining lanes (0

<

-> 1). If DDI E is disabled, DDI A reversal acts

the same as B-D reversal (lanes 0

<

-> 3 and 1

<

->2 are swapped). DDI E does

not support port reversal.
