I have the driver working in devicemode on several boards, but not on an
i.MX51 I think. I have no indication though that the UDC core itself is
in any way different to the ones on other i.MXs.

I have tested usage device mode on i.MX27. It works (Patch for PCM-038
will be sent), but driver(?) does not work for me on i.MX51...
Executing is freeze at dr_controller_setup (drivers/usb/gadget/fsl_udc.c).
Now I trying to check for missing clocks, but not sure about this since we
enable all clocks at start...
So, if anyone can test this feature on i.MX51 it will be helpful.
Thanks.

If there's a problem it's more likely that the usbmisc registers are not
correctly initialized, so it probably won't help to test on another
board

First sucessful work is done.
It is neccesary to set an additional bit in MX5_UTMI_PHY_CTRL_0.
#define MX5_OTG_PHYCTRL_OTG_XCVR_BIT (1 << 7)
...
v |= MX5_OTG_PHYCTRL_OTG_XCVR_BIT;
...
But now it still works only with "fsl-udc" driver, not with "chipidea".
I will continue work on it.
