Hi Samuel,
One of my patch that I sent for 3.9 introduces a bug that fails to
update the port mode hostconfig register. Because of that, the port modes will
always be 0 (i.e. EHCI PHY mode) and other modes will not work. PHY mode will
work, so beagle/panda have no issues.
Since my hardware setup uses only PHY mode, I couldn't catch this problem
earlier.
Below is the fix.

Subject: [PATCH] mfd: omap-usb-host: Actually update hostconfig
The helper functions omap_usbhs_rev1_hostconfig()
and omap_usbhs_rev2_hostconfig() don't write into
the hostconfig register. Make sure that we write
the return value into the hostconfig register.
