Merge tag 'gadget-for-v3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
USB: Gadget: changes for 3.4
This merge is rather big. Here's what it contains:
For am5536udc we have just simple coding style fixes. Nothing that has any
potential to cause any issues going forward.
With mv_udc, there's only one single change removing an unneeded NULL check.
at91_udc also only saw a single change this merge window, and that's only
removing a duplicated header.
The Renesas controller has a few more involved changes. Support for SUDMAC was
added, there's now a special handling of IRQ resources for when the IRQ line is
shared between Renesas controller and SUDMAC, we also had a bug fix where
Renesas controller would sleep in atomic context while doing DMA transfers from
a tasklet. There were also a set of minor cleanups.
The FSL UDC also had a scheduling in atomic context bug fix, but that's all.
Thanks to Sebastian, the dummy_hcd now works better than ever with support for
scatterlists and streams. Sebastian also added SuperSpeed descriptors to the
serial gadgets.
The highlight on this merge is the addition of a generic API for mapping and
unmapping usb_requests. This will avoid code duplication on all UDC controllers
and also kills all the defines for DMA_ADDR_INVALID which UDC controllers
sprinkled around. A few of the UDC controllers were already converted to use
this new API.
