I tried this but it didn't help (neither did reverting ff3187eabb5c
"clk: rockchip: drop CLK_SET_RATE_PARENT from dclk_vop* on rk3568"). On
my display the content is shifted horizontally and the colors are often
wrong.

I am testing this on a RK3568 EVB1, which has a display mounted on the
PCB. I'll submit the patches that add support for this setup soon. For
the time being a preliminary

Tested-by: Michael Riesch <michael.riesch@xxxxxxxxxxxxxx>

Thanks for your work!
Best regards,
Michael
