Just slow down > and get something you can test on hardware. Fair point. The frames in the cover letter were captured on the hardware, but the kernel underneath was the 7.1.5 one this machine runs day to day, with linux-next's CAMSS and CSI2 PHY sources built as modules for it. That is not the same as running linux-next. Before v3 I will boot an actual linux-next kernel on the Surface Pro 11, retest both cameras there, and say exactly what was run. For 4/4 I will also move the fsleep() change into its own patch with the reasoning, and put the lanes_enable() decomposition in a precursor patch, as you asked. Thanks for the reviews of 2/4 and 3/4.
