pxa u2dc driver

[balakrishnan]

Hi,
   I am working on pxa300 based development board and using Linux
2.6.34. In this usb 1.1 device controller driver support "pxa27x_udc" is
available but usb 2.0 device controller driver is not available. Any
patches is there for 2.6.34? or anybody tried for pxa3xx u2dc gadget?

With Regards
J.Balakrishnan

The only available version at the moment is the one provided within Marvell's
BSP. There is currently no support in mainline yet. Igor and Mike have been
working on this for quite a time I think. There is not only the U2D controller
itself, but also the ULPI interface support, and to complicate things
a bit more,
there is also a backward compatibility consideration for U2D + 1.1 Host to
form a strange OTG solution.

I didn't look into that for a long time, but if you are interested in working on
it, please let us know (Cc'ed Igor and Mike).

Just to clear things out.
We are working only on the host side functionality of the U2D and ULPI
drivers,
though keeping in mind future work (ours or anybody else) on the device
side functionality.
