Hello, the imx290 driver specifies 2 tables of link frequencies, depending on number of lanes and the vertical resolution. These numbers vary from 148.5 MHz up to 445.5 MHz. I'm wondering where these number come from, it's not clear for me. Also shouldn't those numbers also depend in bits per pixel and the frames per second? I suspect that the returned link frequency is not correct which breaks things further down using v4l2_get_link_freq(). Best regards Alexander -- i.A.
