This mode needs 80MHz pixel clock which is not in the table for clk-rk3568.c driver. You need a patch similar to https://lkml.org/lkml/2025/3/18/1337 to add this rate. FWIW [email protected] isn't a very common mode

current (with 6.12 kernel) should work fine for your purposes. There might be issues if you are planning to use low-res HDMI display with it. RK356X clock driver uses a table of predefined rates for configuring PLL, so anything that is not in that table won't work. edge (with 6.14) is currently broken for cb2, so don't try it unless you are planning to fix it.
