Clock Root Table (continued) / page 319 Slice Index n = 123 . Currently those IMX8MN_CLK_CSI1_PHY_REF clock are configured to be fed directly from 1 GHz PLL2 , which overclocks them . Instead, drop the configuration altogether, which defaults the clock to 24 MHz REF clock input, which for the PHY reference clock is just fine.
