I am very much responsible for this because of my patch [0] to get all the necessary headers for Tegra234. I was hoping this would be a good thing, but now I see this is a bit of a headache for maintainers. So I am not sure what is a good way to handle this. We would like to get this merged for v6.2, and so please let me know if this is OK with you? Please note that this is similar to the other Tegra USB bindings you have reviewed for v6.2.

I think it'd be best for me to pick these up into the Tegra tree where the dependency exists and where I already have the XUSB bindings conversion patches for earlier chips. Looks like this is also not very different from, say, the Tegra194 XUSB bindings, so should fit right in there. Thierry
