A gentle reminder for patches 8 through 12 of this series, which I guess
would ideally be taken by you. Since the merge window is approaching, do
you think it's feasible to iterate a second pull request to Arnd with my
patches too?

With respect to your devicetree/next branch, my patches have the following
conflicts:

PATCH 9:
- arch/arm64/boot/dts/broadcom/bcm2712-rpi-5-b.dts: &pcie1 and &pcie2
  reference at the end, my patch was rebased on linux-next which has them
  while your devicetree branch has not. This is trivial to fix too.

PATCH 9 and 10:
- arch/arm64/boot/dts/broadcom/Makefile on your branch has a line recently
  added by Stefan's latest patch for RPi2. The fix is trivial.

PATCH 11 and 12:
- arch/arm64/configs/defconfig: just a couple of fuzz lines.

Please let me know if I should resend those patches adjusted for your tree.

Many thanks,
Andrea
