Is that meant to imply that this patch fixes the copy of the binding doc
in U-Boot so it does match the kernel's copy?

The file is named pl011.txt in the kernel. Shouldn't U-Boot's copy be
named the same?

I don't see either "clock" or "clock-frequency" mentioned in the Linux
binding doc.

It'd be worth mentioning which version of Linux this binding doc came
from; that text has changed in linux-next since v4.1 which is what I
assume you're importing.

That looks like an unrelated change.
