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.
I think Marek has posted some rcar3 updates to support the PCIe. I am hopeful that it will work on the RZ/G2 series. I have rpc-spcif enabled and my plan was to post some updated configs with it enabled once the updated configs had been merged.
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 had not thought of that, but I can take a look at it.
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.
I will do a V2 today.
