Hi Marek,

You're right. I have a set of messy patches pulled from nxp's u-boot
that is enabling PCI ECAM and enetc. With the latest patchset from
Alice PCI isn't there yet.

Yes, I did get USB 2.0 by adding the relevant usb2 nodes to dt
(haven't seen this submitted upstream yet) and your "usb: ehci-mx6:
Add i.MX95 support" patch.

Ok, the usb3 dt nodes have been submitted upstream [1] but I haven't
gotten usb3 to work as host yet but did not try peripheral mode. I did
notice there is no ptn5110 driver keeping type-C role selection
working.
