Thank you for answering. I did try a Kernel from 1 year ago (11. December 2020 - with the Hash b5206275b46c30a8236feb34a1dc247fa3683d83). But this Kernel had the exact same behavior. I even wanted to go back further the when the tcpm module got it's own subdirectory (v4.20 - 20. September 2018 - Hash ae8a2ca8a2215c7e31e6d874f7303801bb15fbbc) to see if it still worked at that time but my build system was not able to build it.

Hello
For a few weeks now I am trying to make the PTN5110 chip work with the new Kernel 5.15.74. The same hardware setup was working with the 4.19.72 Kernel. The steps I took so far are as follows:
That is a huge jump. Why not use 'git bisect'?
Or start with a smaller jump. Why not go to 5.4.y first, that's only a year's worth of changes, instead of 4 years of changes.
thanks,
