Do we have usb2_clksel support in u-boot? If yes, it make sense to import from 5.12-rc1.
Similarly for other bits importing from kernel 5.12-rc1.

May be rpc-spcif support available in u-boot. So we could import from 5.12-rc1.
For  others like PCIe, ethernet the changes corresponding to dts is not present in driver.

Do we have any plans to update the driver or plan to delete the properties/nodes
from U-boot specific dtsi, so that we can save image size?

As Marek, suggested please send V2.
