Hi Alan,

Hi!
I'm currently seeing a problem on an OMAP3530 based board (Technexion
TAO3530). Where the MUSB is configured as device/peripheral and the
ethernet gadget is compiled into the kernel. This works without any
problems and usb0 is available when the USB cable is connected to a PC
upon startup

I am developing a usb perihperal with the goal of high data throughput
on a freescla i.Mx6 (phyFlex).
My current UDC driver is "fsl-usb2-udc" on kernel 3.0.35.
I was recommended the chipidea driver introduced in kernel 3.5 since
it would perform better.
Currently I have speed issues when I use gadg

Patch : 14982e3 USB: OHCI: Properly handle ohci-exynos suspend
has already removed 'ohci_hcd' settings from exynos glue layer
as a part of streamlining the ohci controller's suspend.
So we don't need the locks for 'ohci_hcd' anymore.
