The Q64-B test results were a bit different from Rock64's, but this patch set 
enabled the 4K at 60Hz resolution as well.

1. The console output was at 1080p, whereas it also switched to 4K on the 
Rock64. I actually prefer this behavior.
2. After starting sway, it did switch to a 4K resolution, but this time it 
selected 4096x2160 at 30Hz on an unpatched kernel (my 6.10-rc2 and Debian 6.9.7).
With my 6.10-rc5 kernel *with* this patch, it selected 3840x2160 at 60Hz
3. None of those 'other' issues I reported with Rock64 showed up on Q64-B :-D

IOW: Also for the Pine64 Quartz64 Model B, you can add:
