I'm testing these patches with an AM33xx board that has the first musb
port wired to an USB type A plug, but it doesn't yet work for me.

The messages I'm getting are:

[    1.219339] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
[    1.226568] ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver

[    1.262940] musb-hdrc: 28/31 max ep, 16384/16384 memory

So there is no host interface registered. I'm unsure on how to fix this,
and I didn't get an answer yet to that question when I asked Felipe
about how interface drivers like dsps are supposed to act in order to
get host mode back after the recent musb cleanups.

What type of hardware do you test this with? Does host mode work for you?


Many thanks,
Daniel
