Russell King 0996391139 ARM: Fix lubbock defconfig build
drivers/built-in.o: In function `pxa25x_udc_probe':
drivers/usb/gadget/pxa25x_udc.c:2195: undefined reference to `otg_get_transceiver'
drivers/usb/gadget/pxa25x_udc.c:2300: undefined reference to `otg_put_transceiver'

pxa25x_udc.c unconditionally uses these two functions, so we need to
ensure that the object providing them is also built.

Magnus Damm 59c82d12aa usb: r8a66597-udc unaligned fifo fix
Rework the r8a66597-udc fifo code to avoid unaligned accesses.

Without this patch unaligned exceptions will degrade the
USB performance. The exceptions come from the fact that
the usb fifo data buffers may be misaligned.

This patch updates the fifo access code to only use
insl()/outsl() and insw()/outsw() in the case of properly
aligned data buffers. The fallback case is that inl()/inw()
are used for misaligned buffer reads together with outb()
that is used for misaligned buffer writes.

Brian Niebuhr 9b39e9dded USB: gadget: Add EEM gadget driver
This patch adds a CDC EEM ethernet gadget driver.  CDC EEM is a newer
USB ethernet specification that uses a simpler interface than the older
CDC ECM.  This makes CDC EEM usable by a wider set of USB hardware.
By default the ethernet gadget will still use CDC ECM/Subset, but kernel
configuration and/or a module parameter will allow alternative use of
the CDC EEM protocol.

Changes since last version:
	- Brought in missing RNDIS changes that caused compile error
	- Modified 'sentinel CRC' checking to match EEM host driver

Robin Callender e792b1b0b8 USB: gadget: audio driver seg-fault fix
The included patch can be applied to the new usb gadget audio driver.

It addresses a seg-fault in uncovered in g_audio.ko.
The fault occurs in the function u_audio.c::gaudio_open_end_dev() when
device /dev/snd/pcmC0D0c (FILE_PCM_CAPTURE) is not present.

I suspect there may be similar problems with device /dev/snd/pcmC0D0p
(FILE_PCM_PLAYBACK) handling also.  I leave that for the developer(s),
as I was unsure as to the side-effects of not calling
playback_default_hw_params() in the initialization phase.

Alan Stern e9238221d3 USB: dummy-hcd: accept mismatch between wLength and transfer length
This patch (as1269) fixes a bug in the way dummy_hcd handles control
URBs.  Currently it returns a -EOVERFLOW error if the wLength value in
the setup packet is different from the URB's transfer_buffer_length.

Other host controller drivers don't do this.  There's no reason the
two length values have to be equal, and in fact they sometimes aren't
-- a driver might set the transfer length to the maxpacket value in
order to handle buggy devices that don't respect wLength.

This patch simply removes the unnecessary check and error return.

Philipp Zabel ab26d20f3e USB: gadget: pxa25x: basic transceiver support
This adds very basic otg_transceiver support, with vbus_session
and vbus_draw callbacks.

Now VBUS sensing can be handled by an external driver which registers
the otg_transceiver interface. It also allows gadget drivers to configure
the current drawn from VBUS. The UDC driver just passes their requests
along to the transceiver driver.
