Great, care to send a patch to U-Boot that aligns this cubox dts with upstream?

I do have a preliminary patch that syncs all imx6dl/q dts with upstream.

I haven't submitted it yet, as it needs lots of careful manual
inspection, especially with the alias nodes.

Still want to submit it, but it is not a trivial one due to the high
chances of boot regressions.

Thanks
