This file is not necessary. When rk3568-easepi-r1-u-boot.dtsi is 
missing, rk3568-u-boot.dtsi will be automatically included, which in 
turn automatically includes rk356x-u-boot.dtsi.

Then you don't need this line either.

Do you really need this?

Do you really need to remove clock-names from the xPL DTB? I know most 
Rockchip configs do it but I think it's mostly because everybody's 
copying everybody :)

Looking good otherwise, thanks for the patch!
