Merge tag 'usb-for-v3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
Felipe writes: usb: patches for v3.19 merge window This time, a very pull request with 216 non-merge commits. Most of the commits contained here are sparse or coccinelle fixes ranging from missing 'static' to returning 0 in case of errors. More importantly, we have the removal the now unnecessary 'driver' argument to ->udc_stop(). DWC2 learned about Dual-Role builds. Users of this IP can now have a single driver built for host and device roles. DWC3 got support for two new HW platforms: Exynos7 and AMD. The Broadcom USB 3.0 Device Controller IP is now supported and so is PLX USB338x, which means DWC3 has lost is badge as the only USB 3.0 peripheral IP supported on Linux. Thanks for Tony Lindgren's work, we can now have a distro-like kernel where all MUSB glue layers can be built into the same kernel (statically or dynamically linked) and it'll work in PIO (DMA will come probably on v3.20). Other than these, the usual set of cleanups and non-critical fixes. Signed-off-by: Felipe Balbi <balbi@ti.com>
