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? > > I can submit a V2 with the binding file included, or I can submit the > > dt-binding file now and wait on the Beacon boards until that file has > > been merged, or I can redo the device tree in a custom way to work the > > 5.10 and not use the veraclock dt-bindings since there is no > > versaclock driver in U-Boot anyway.
