Thanks, I was already on CC. That series does not affect the board
features as configured in this patch. However, we are eagerly awaiting
ISCCG and then PRU Ethernet support in upstream as this is used on our
boards, with both SR1.0 and (upcoming) SR2.0.

However, I can update [1] with that series and retest our staging
integration. But as you can see from the topmost commit, it is
constantly shaking as upstreaming goes on.
