Somehow, I was missing some of Ajay's patches. I resolved that, and now
the series applied.

However, I needed to add a phandle "usb0-phy = <&usb0_phy>" to the
usb_otg_hs DTSI block, otherwise devm_usb_get_phy_by_phandle() in
drivers/usb/musb/musb_dsps.c would fail. Is that correct? I can't seem
to find that in your patches.

With this addition, I see the following:

[    1.782180] musb-hdrc: version 6.0, ?dma?, otg (peripheral+host)

... but no USB functions. Also, every two seconds, the following message
is printed:

[   15.052196] musb_bus_suspend 2308: trying to suspend as a_wait_vrise
while active

Anything obvious that I'm missing?
