Merge tag 'usb-for-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes:
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.
