Peichen Huang 230dced3e2 drm/amd/display: improve dpia pre-train ... [WHY] We see unstable DP LL 4.2.1.3 test result with dpia pre-train. It is because the outbox interrupt mechanism can not handle HPD immediately and require some improvement. [HOW] 1. not enable link if hpd_pending is true. 2. abort pre-train if training failed and hpd_pending is true. 3. check if 2 lane supported when it is alt mode Reviewed-by: Wenjing Liu <wenjing.liu@amd.com> Reviewed-by: Meenakshikumar Somasundaram <meenakshikumar.somasundaram@amd.com> Signed-off-by: Peichen Huang <PeiChen.Huang@amd.com> Signed-off-by: Tom Chung <chiahsuan.chung@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>		2025-01-10 12:12:29 -05:00
