 "Here's the big USB merge for 3.9-rc1

  Nothing major, lots of gadget fixes, and of course, xhci stuff.

  All of this has been in linux-next for a while, with the exception of
  the last 3 patches, which were reverts of patches in the tree that
  caused problems, they went in yesterday."

	usb: xceiv: patches for v3.9 merge window

	Two new PHY drivers coming here: one for Samsung,
	one for OMAP. Both architectures are adding USB3
	support to mainline kernel.

	The PHY layer now allows us to have mulitple PHYs
	of the same type, which is necessary for platforms
	which provide more than one USB peripheral port.

	There's also a few cleanups here: removal of __dev*
	annotations, conversion of a cast to to_delayed_work(),
	and mxs-phy learns about ->set_suspend.

	usb: musb: patches for v3.9 merge window

	Mostly fixes all over which weren't urgent enough for
	the late -rc cycle.

	There is a Double Buffering fix for Host Mode TX,
	a dependency fix for the transceiver driver, some
	fixes to the error path and a fix for the use of
	omap_musb_maibox.

	Other than these fixes, there a removal duplicate
	headers from the dsps glue layer and removal of
	redundant assignments in omap2430_probe().

c11747f6ce usb: musb: omap: make use of the new PHY lib APIs
New PHY lib APIs like usb_add_phy_dev() and devm_usb_get_phy_dev() are
used in MUSB (OMAP), in order to make use of the binding information
provided in the board file (of OMAP platforms).

All the platforms should be modified similar to this to add and get the
PHY.

148e11349b usb: Convert to devm_ioremap_resource()
Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.

devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

091a62c9b3 usb: musb: cppi_dma: drop '__init' annotation
This patch fixes the following:

WARNING: vmlinux.o(.text+0x1e709c): Section mismatch in reference from the funct
ion dma_controller_create() to the function .init.text:cppi_controller_start()
The function dma_controller_create() references
the function __init cppi_controller_start().
This is often because dma_controller_create lacks a __init
annotation or the annotation of cppi_controller_start is wrong.

This warning is there due to the deficiency in the commit 07a67bbb (usb: musb:
Make dma_controller_create __devinit).

Since the start() method is only called from musb_init_controller() which is
not annotated, drop '__init' annotation from cppi_controller_start() and also
cppi_pool_init() since it gets called from that function, to avoid another
section mismatch warning...

Commit 00a0b1d58a (usb: musb: omap: Add device
tree support for omap musb glue) assigns result of devm_kzalloc() call to
the 'config' variable but then checks for NULL the 'data' variable (already
checked after previous call). Thus we risk a kernel oops further when data
pointed by 'config' is written to by subsequent of_property_read_u32() calls
iff the allocation happens to fail...

a70b84421b usb: musb: Double buffering issues in host mode TX
Whenever an URB is programmed for transfer, the TXFIFO
is flushed. This results in valid packets of the
previous transfer to get flushed when double buffering
is enabled (The MUSB_TXCSR_FIFONOTEMPTY bit in TXCSR
is set indicating that a packet in the FIFO is yet to be sent)
For ex:- In Host mode Audio, noise is heard in the headset
when double buffering is enabled on the ISO endpoint.
The fifo flush is removed for double buffering case.
The fifo is now flushed only in cases of error or when
aborting a transfer.

Also, In Host MSC case, data toggle errors are seen when double
buffering is enabled on the bulk endpoint. Whenever an URB is
programmed for transfer, the data toggle is set manually
resulting in data toggle errors on the bus. Leave the data
toggle handling upto the hardware in the double buffering case.

Felipe says:
	usb: fixes for v3.8-rc2

	Here is the first set of fixes for v3.8-rc cycle.

	There is a build fix for musb's dsps glue layer caused
	by some header cleanup on the OMAP tree.

	Marvel's USB drivers got a fix up for clk API usage
	switching over to clk_prepare() calls.

	u_serial has a bug fix for a missing wake_up() which
	would make gs_cleanup() wait forever for gs_close()
	to finish.

	A minor bug fix on dwc3's debugfs interface which
	would make us read wrong addresses when dumping
	all registers.

	dummy_hcd learned how to enumerate g_multi.

	s3c-hsotg now understands that we shouldn't kfree()
	memory allocated with devm_*.

	Other than that, there are a bunch of other minor fixes
	on renesas_usbhs, tcm_usb_gadget and amd5536udc.

	All patches have been pending on mailing for many weeks
	and shouldn't cause any problems.

deeeb9ee1e usb: musb: dsps: header movement build error fix
"54db6ee ARM: OMAP2+: Introduce local usb.h" moved control module bit
definitions from plat/usb.h (which dsps glue was using) to a local
header in mach-omap2. And in parallel,
"c68bb4c usb: musb: dsps: control module handling (quirk)" added
control module handling capability to dsps glue driver that used
those control module bit definitions.

Integration of above two changes would cause build error in musb dsps
glue driver (they go through different trees upstream) as is seen now
in linux-next. Fix it by adding necessary definitions in dsps glue
driver.

45c3eb7d3a ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h
Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.

Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.

So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.

The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.

Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.

Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.

Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.

Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

While removing g_file_storage, we also had to fix a bunch

macro in order to reduce some boilerplate code from all glue
layers.

Other than that, we had a series fixing one known silicon errata
where we couldn't read a few registers. In order to fix that
we're now using shadow variables for reads and only writing
to the registers which are known to break functionality when
read."

d75542263a Revert "usb: musb: dsps: remove explicit NOP device creation"
This reverts commit d8c3ef256f.

Above mentioned change was made along with multi usb phy change and
adding DT support for nop transceiver. But other two changes did not
make it to mainline. This in effect makes dsps musb wrapper unusable
even for single instance.

Hence revert it so that at least single instance can be supported.

baef653a50 usb: musb: remove generic_interrupt
This patch is based on the discussion of a previous patch to fix an issue
where the omap2430 musb driver is not working for N9/N950.

Moving all the interrupt handling to the devices. Avoids inclusion of generic
interrupt and breakage due to sometimes misleading CONFIG options. This makes
sure usb always works if on of the subdrivers is chosen. Tested on Nokia N9/N950.

Partially clean up CONFIG_SOC_OMAP3430 which is not necessary in the cases
where I removed it. Also helps with the removal work of those options that
Tony Lindgren predicted would happen at some point.

c68bb4c679 usb: musb: dsps: control module handling (quirk)
am335x uses nop transceiver driver and need to enable builtin phy
by writing into usb_ctrl register available in system control
module register space. This is being added at musb glue driver
layer until a separate system control module driver is available.

Proper solution is to make use of control module driver, but it is
not expected to be ready soon.

Other options available are providing control module register space
as memory resource via DT or using omap hwmod.

DT approach has been rejected by Rob Herring, while resources are
being moved from hwmod to DT. And both of the above approaches
require that control module registers be configured in wrapper
itself requring a quirk in driver as well as DT or hwmod.

Here another option is used, providing driver with control module
register physical address. Even though this a hack, there is no other
option left till control module driver is ready. As of now only
am335x is using dsps wrapper, and so driver is made aware of am335x
control module physical address.

Please note that this is a temporary arrangment till omap control
module driver is available.

3b46dd76a9 usb: musb: dsps: reduce musb instance to one
Currently multiple phy's of the same type are not supported, hence
reduce musb instances to one. This helps in supporting at least one
instance of musb, rather than having none. Even without this, it was
observed that both instances were working (by luck), but this holds
good iff wrapper is part of Image. And it is not correct for both
controller's to be associated with same phy, here it was working
because phy is a nop one. And having wrapper as a module and
rmmod'ing would crash.

This can be reverted once multi phy support for same type is available
and driver is enhanced to make use of it.
