[PATCH v4] drm/i915/display/lspcon: Increase LSPCON mode settle timeout

2023-10-02 Thread Niko Tsirakis
This is to eliminate all cases of "*ERROR* LSPCON mode hasn't settled", followed by link training errors. Intel engineers recommended increasing this timeout and that does resolve the issue. On some CometLake-based device designs the Parade PS175 takes more than 400ms to settle in PCON mode. 100 r
