The patches look good to me. I have build-tested this with the snippet
below and my series from
https://lore.kernel.org/all/20260907090956.2825703-2-arnd@xxxxxxxxxx/
to check that no use of the legacy interfaces remain.
You can probably fold my one-liner into your last patch.

There is a trivial conflict between your series and my patch 2/2
"gpiolib: remove linux/gpio.h", but if yours gets merged, I can
resend mine without that line.

I would guess even with access to hardware testing is going to be
challenging, I noticed that the defconfig kernel does not fit on the
4MB flash any more (even without rootfs), and the USB support was
never added for rsk7203, only for 7264/7269.
