Should this have more complete compatible listed, too, for the
unlikely case hardware problem is discovered?

Controller is compatible with the generic OHCI driver as of now there are no known hardware limitations. If in future if we come encounter any hardware issue we will add SoC specific platform string with the fix.

Hope this is OK with you.

Cheers,
