Sascha, I have tested your patchset, it works after adding a few of changes
at my otg patchset (we still need to read otgsc for gadget-only function).
I use my mx6q sabrelite board to test.

I have tested all roles with below diff:
So, feel free to add my Tested-by: Peter Chen <peter.chen@freescale.com>

Besides, if you have a mx51 bbg board, you can test id-switch function.
For mx5x, you may need a phy driver.

My git: https://github.com/hzpeterchen/linux-usb.git master

It is based on your tag, and add latest otg patch.
Besides, it has Michael Grzeschik/Marc Kleine-Budde
usb misc patch as well as my platform changes for mx6q board.
