The log you posted should be sufficient. I'm not sure about a timeline for a fix, however.
Couldn't you just reverse the commits ?
I did complete the bisection btw:
691f2d763d0731224439686ecf2d440df8fe910e is the first bad commit commit 691f2d763d0731224439686ecf2d440df8fe910e Author: Mikita Lipski mikita.lipski@amd.com Date: Fri Jul 13 09:07:35 2018 -0400
drm/amd/display: update clk for various HDMI color depths
commit 81aca8e75c1b046865fb2badef95a0dcff6f73de upstream.
[why] When programming tonga's connector's backend we didn't take in account that HDMI's colour depth might be more than 8bpc therefore we need to add a switch statement that would adjust the pixel clock accordingly.
[how] Add a switch statement updating clock by its appropriate coefficient.
