2013-04-09USB: regroup all depends on USB within an if USB blockFlorian Fainelli
This patch removes the depends on USB from all config symbols in drivers/usb/host/Kconfig and replace that with an if USB / endif block as suggested by Alan Stern. Some source ... Kconfig lines have been shuffled around to permit a better regroupment of the Kconfig files depending on "config USB" item. No functionnal change is introduced.

Other than these, there's the usual set of cleanups: s3c UDCs are moving over to devm_regulator_bulk_get() API, at91_udc removed an unnecessary check for work_pending() before scheduling and there's the removal of an unused variable from uac2_pcm_trigger().

The NCM gadget got an endianness fix and the Ethernet gadget a frame size fix. We're finally removing the g_file_storage gadget and sticking to g_mass_storage and the new tcm_usb_gadget gadgets since that was a huge duplicaton of effort anyway. While removing g_file_storage, we also had to fix a bunch of defconfigs which were still pointing to the old gadget. There's a big series getting us closer to being able to introduce our configfs interface. The series converts functions into loadable modules which will, eventually, be registered to the configfs interface. Other than that there's the usual typo fixes and miscelaneous cleanups all over the place."
2012-11-08usb: renesas_usbhs: use transfer counter if IN direction bulk pipeKuninori Morimoto
received data will break if it was bulk pipe and large data size, because pipe kept BUF PID even though it doesn't have enough buffer. To avoid this issue, renesas_usbhs can use transfer counter. Pipe PID will be NAK if it didn't have enough buffer by this patch. renesas_usbhs has strange address mapping. Thus, it is difficult to calculate transfer counter setting address.

2012-11-06usb: renesas_usbhs: host: add endpoint user counterKuninori Morimoto
renesas_usbhs attaches pipe to endpoint when urb was queued, and it will be detached when transfer was done. Multi device controlling was enabled by this behavior. Now renesas_usbhs driver tried to wait until detaching if urb was queued to endpoint which already has been attached to pipe, and it created strange driver behavior. But it can re-use this attached pipe if multi urb was queued. This patch implements it. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

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. Conflicts: drivers/usb/dwc3/gadget.c

2012-02-14usb: renesas: fix scheduling in atomic context bugGuennadi Liakhovetski
The current renesas_usbhs driver triggers BUG: scheduling while atomic: ksoftirqd/0/3/0x00000102 with enabled CONFIG_DEBUG_ATOMIC_SLEEP, by submitting DMA transfers from an atomic (tasklet) context, which is not supported by the shdma dmaengine driver. Fix it by switching to a work. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
2012-02-14usb: renesas_usbhs: (cosmetic) simplify list operationsGuennadi Liakhovetski
list.h already provide helpers to find the first entry and to move list nodes to the tail of another list. This patch simply uses those helpers, no functional changes. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
2012-01-24usb: renesas: silence uninitialized variable report in usbhsg_recip_run_handle()Jesper Juhl
In drivers/usb/renesas_usbhs/mod_gadget.c::usbhsg_recip_run_handle() the Coverity Prevent checker currently flags a warning about possibly uninitialized use of 'ret' i usbhsg_recip_run_handle(). It does this since it assumes we take one of the non-default branches in the switch and then subsequently take the false branch in the 'if (func)' case below. This exact scenario will never happen, but Coverity can't see that for some reason. This patch initializes 'ret' to '0' when it is declared which should shut up this report and won't really hurt - so why not? At least then it's clear that 'ret' is always initialized..
