Dear Ilya Yanok,

> Current MUSB driver in U-Boot uses old UDC API while new gagdet
> client drivers need new gadget API. Also current MUSB driver has
> some significant limitations (like inability to handle tx for
> endpoints other than ep0). So I think port of new Linux driver is
> desirable.
> 
> This is initial port, performed mostly by putting DM and OTG
> code under #ifndef __UBOOT__ clauses. My intention was to be as
> close as possible to the original to ease of possible resyncs.
> Some warnings are suppressed via CFLAGS. There are some style
> problems but I'm not touching them for now for the above mentioned
> reason. There is obviously some room for optimisation, some
> structure fields are unused as well as (probably) some code.
> 
> This is not a replacement for existing MUSB driver (at least for
> now), cause there are still consumers of USB serial gadget which
> uses old API and there is no support for serial with new API
> for now.
> 
> OTG and DMA are not supported. Ported drivers include:
> musb_dsps (should work both with TI AM33xx and TI81xx, tested only on
> AM33xx), am35x (tested on AM3517 EVM) and omap2plus (should work on
> OMAP2/3/4, tested on omap3_beagle, omap4_panda doesn't work and needs
> more work). Others should be easy to port too.
> 
> Virtual root hub is not implemented but this shouldn't be
> a big problem as the old code has virtual root hub support
> enabled only for Blackfin platform.
> 
> Pathes are rather big because of the original code size (and I didn't
> delete unused code, just disabled it). So it's probably better to
> look at changes as compared to Linux code. I prepared such version
> also, you can find it at [1]. Hopefully it will be also useful
> if resync with the kernel will be needed in future.

What is this patchset ? I received another similar one, but which is more 
complete ...
