Hi Marek and Simon,

This series started out with the idea that it would be a nice small project for the weekend, but it turned out to be a bit more work...

The main purpose of this series is to convert the musb host mode code to the device-model this has also resulted in various usb fixes / cleanups / reworking to make this possible, both in the generic usb code as well as in the device model usb code.

Given that this touches both, I think it is probably best to merge the first 15 patches through Simon's tree like we did last time, then once those are place I can merge the sunxi bits. Note this is intended for v2015.10 (ofcourse).

Note that this series is useful for a bunch more boards then just the single one the last patch updates to use musb + ehci + ohci, but that is the one I've been testing with other defconfig-s will be updated with followup patches.

Please review.

Thanks for putting this together. Actually I'm not sure what musb is. Can you explain what it is used for - it seems to be referred to as a new version of something else. Why do we have musb and non-musb? Is there a README somewhere I could read?

p.s.

As for there being both a drivers/usb/musb and a driver/usb/musb-new directoyry, I believe that they both are drivers for the same hardware, but not all boards have been ported to musb-new yet. musb-new is derived from recent kernel code for the musb controller.

Regards,

Hans
