4K@60Hz mode rejected due to CLOCK_HIGH

I have a new Framework laptop running Fedora 35, stock distro kernel package 5.14.16-301, BDB version 240.

My CPU/GPU is an 11th gen i7-1165G7, connected via a USB-C-to-DP cable to a 2014-era Dell P2715Q monitor that supports 3840x2160@60Hz over DP (my Mac drives it this way just fine).

With i915 debugging enabled, I can see the 4K mode being detected and discarded during boot due to CLOCK_HIGH.

I'll attach some log files shortly.
