We typically have the .dts{,i} changes in a separate patch. I suggest
doing the same here.
I also have two questions about this part:
- why are these not referenced by the SPICC controller node?
- is there a particular reason why meson-gxl.dtsi is updated but
meson-gxbb.dtsi is not? (my understanding is that GXBB is also lacking
hardware OEN support)


Best regards,
Martin
