7fd94beeca usb: gadget: patches for v3.8
renesas_usbhs implements ->pullup() method, switches over
 to devm_request_irq(), adds support for DMA Engine and
 got a few miscelaneous cleanups.
 
 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.

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.

2f77116425 usb: musb: remove hand-crafted id handling
This replaced the handcrafted id handling by the PLATFORM_DEVID_AUTO
value which should do the same thing.

This patch probably also fixes ux500 because I did not find the "musbid"
variable to remove. And we close a tiny-unlikely race window becuase the
old code gave the id back before device was destroyed in the remove
case.

The res_name is used for the name construction of a DT property as
follows:

  sprintf(res_name, "port%d-mode", id);

Hence, res_name must be at least 11 characters long in order to store
the name including the terminating '\0'.

While at it, use to snprintf() rather than sprintf() when accessing this
buffer.

On AM3517, tx and rx interrupt are detected together with
the disconnect event. This generates a kernel panic in musb_interrupt,
because rx / tx are handled after disconnect.
This issue was seen on a Technexion's TAM3517 SOM. Unplugging a device,
tx / rx interrupts together with disconnect are detected. This brings
to kernel panic like this:

Note: this behavior is not seen with a USB hub, while it is
easy to reproduce connecting a USB-pen directly to the USB-A of
the board.

Drop tx / rx interrupts if disconnect is detected.

9cd11c0c47 ARM: soc: multiplatform enablement
This is a pretty significant branch. It's the introduction of the
 first multiplatform support on ARM, and with this (and the later
 branch) merged, it is now possible to build one kernel that contains
 support for highbank, vexpress, mvebu, socfpga, and picoxcell. More
 platforms will be convered over in the next few releases.
 
 Two critical last things had to be done for this to be practical and
 possible:
 * Today each platform has its own include directory under
   mach-<mach>/include/mach/*, and traditionally that is where a lot of
   driver/platform shared definitions have gone, such as platform data
   structures. They now need to move out to a common location instead,
   and this branch moves a large number of those out to
   include/linux/platform_data.
 * Each platform used to list the device trees to compile for its
   boards in mach-<mach>/Makefile.boot.
 
 Both of the above changes will mean that there are some merge
 conflicts to come (and some to resolve here). It's a one-time move and
 once it settles in, we should be good for quite a while. Sorry for the
 overhead.

     of driver/platform shared definitions have gone, such as platform
     data structures.  They now need to move out to a common location
     instead, and this branch moves a large number of those out to
     include/linux/platform_data.
   * Each platform used to list the device trees to compile for its
     boards in mach-<mach>/Makefile.boot.

  Both of the above changes will mean that there are some merge
  conflicts to come (and some to resolve here).  It's a one-time move
  and once it settles in, we should be good for quite a while.  Sorry
  for the overhead."

Fix conflicts as per Olof.

61464c8357 ARM: soc: general cleanups
This is a large branch that contains a handful of different cleanups:
 
 - Fixing up the I/O space remapping on PCI on ARM. This is a series
   from Rob Herring that restructures how all pci devices allocate I/O
   space, and it's part of the work to allow multiplatform kernels.
 - A number of cleanup series for OMAP, moving and removing some
   headers, sparse irq rework and in general preparation for
   multiplatform.
 - Final removal of all non-DT boards for Tegra, it is now
   device-tree-only!
 - Removal of a stale platform, nxp4008. It's an old mobile chipset
   that is no longer in use, and was very likely never really used with
   a mainline kernel. We have not been able to find anyone interested
   in keeping it around in the kernel.
 - Removal of the legacy dmaengine driver on tegra
 
 + A handful of other things that I haven't described above.

Fix up some conflicts with the staging tree (and because nxp4008 was
removed)
