I picked a DT sync for Linux 5.10 from Biju (on CC), does your board need something from 5.12-rc1 or can it be based on 5.10 too ?
I honestly don't remember. I had to unexpectedly leave town for this week due to a funeral, and I won't be near a Linux development computer to run tests until Feb 1, so I don't know if the board will build using 5.10 or not. Sorry I don't have a better answer.
Lets revisit this later then.
I tested the Beacon boards, but they have a dependency on usb2_clksel that is not present in the 5.10 device tree. I also noticed that I forgot to include versaclock.h dt-binding file from the kernel, so the Beacon boards don't build for that too.
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. You may have an alternative as well.
Can you try to figure out the best option with Biju , who is in charge of all the RZG stuff ? Either way works for me.
You also likely want to roll V2 out soon, since the RC1 is out. I would still like to pick it for 2021.04 .
As Marek, suggested please send V2.
Regards, Biju
