happens intermittently. link configuration <1, 1.62> could not support
4k mode. dp safe mode 640x480@60hz could be used for all link
configuration test.

[Hersen] DP safe mode is defined within DP specification and DP Link Layer Compliance Test Specification.
Also, after set to this safe mode this test stop to be intermittently?
{Hersen] Run 30 loops of test, the issue could not be reproduced.

For DP bandwidth vs video timing, you please refer to https://en.wikipedia.org/wiki/DisplayPort
Here is rough calculation of video timing and DP lane bandwidth.
video mode timing needs bandwidth in bits:
pixel_clock x bit_per_color x 3
3840x2160@60hz pixel clock could be 594Mhz. For bits_per_color =8.
594x1,000,000 x 8 x 3 = 14,256 x 1,000,000
DP lane support bandwidth in bits. Be aware that 10 bits of DP lane (including control bit etc.) consists of 1 DP symbol (8bits).
20 percent of DP lane bandwidth is used for control, not for pixel data.
(link_rate X Lane_count) * (8 /10)
<1 Lane, 1.62GHz> DP lane:
((1 x 1.62 x 1,000,000,000) * (8 /10) = 1,296 x ,1000,1000
