[GIT PULL] USB patches for v4.3 merge window

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Greg,

here's the big Gadget pull request. It contains 146 non-merge commits this
time around.

All patches have been soaking in next for quite a while and have also been
tested with the platforms I have around.

Let me know if you want anything to be changed.

cheers

  usb: musb: gadget: fix build break by adding missing 'break' (2015-08-07 09:25:46 -0500)

usb: patches for v4.3 merge window

New support for Allwinne SoC on the MUSB driver has been added to the list of
glue layers. MUSB also got support for building all DMA engines in one binary;
this will be great for distros.

DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
maxpacket size transfers are > 512 bytes.

Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
now required to set these flags up when adding endpoints to the framework.

Other than these, we have the usual set of miscelaneous cleanups and minor
fixes.
