That's a very low number of quirks.. Should we have some more?
Should it also be marked dma-coherent?
Identical comments for the second instance.

I would actually like to add these as well, but there is no precedent in
upstream as to what quirks to add for usb nodes, so I kept only a couple
of them. Ideally downstream we disable u1u2 for almost all targets
because of some issues in the past. (atleast during tethering use cases,
but I need to double check though).

ACK.

Does
5b8baed4b881 ("arm64: dts: qcom: sc7180: Disable SuperSpeed instances in park mode")
apply here too?
