git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc multiplatform enablement from Olof Johansson:
"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."
Fix conflicts as per Olof.

Pull USB changes from Greg Kroah-Hartman:
"Here is the big USB pull request for 3.7-rc1
There are lots of gadget driver changes (including copying a bunch of
files into the drivers/staging/ccg/ directory so that the other gadget
drivers can be fixed up properly without breaking that driver), and we
remove the old obsolete ub.c driver from the tree.
There are also the usual XHCI set of updates, and other various driver
changes and updates. We also are trying hard to remove the old dbg()
macro, but the final bits of that removal will be coming in through
the networking tree before we can delete it for good.
All of these patches have been in the linux-next tree.

into next/multiplatform
Enable initial ARM multi-platform support for highbank, mvebu,
socfpga, picoxcell, and vexpress.
Multi-platform support is dependent on mach/gpio.h removal and
restructuring of DEBUG_LL and dtb build rules included in this branch.
This has been built for all defconfigs, and booted on highbank with
all 5 platforms enabled.

usb: gadget: patches for v3.7 merge window
This pull request is large but the biggest part is the first part
of the cleanup on the gadget framework so we have a saner setup
to add configfs support for v3.8.
We have also some more conversions to the new udc_start/udc_stop
which makes us closer from dropping the old interfaces.
USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED are finally gone,
thanks to Michal for his awesome work.
Other than that, we have the usual set of miscellaneous changes
and cleanups involving improvements to debug messages, removal
of duplicated includes, moving dereference after NULL test,
making renesas_hsbhs' irq handler Shared, unused code being dropped,
prevention of sleep-inside-spinlock bugs and a race condition fix
on udc-core.

The bcdDevice field is defined as
|Device release number in binary-coded decimal
in the USB 2.0 specification. We use this field to distinguish the UDCs
from each other. In theory this could be used on the host side to apply
certain quirks if the "special" UDC in combination with this gadget is
used. This hasn't been done as far as I am aware. In practice it would
be better to fix the UDC driver before shipping since a later release
might not need this quirk anymore.
There are some driver in tree (on the host side) which use the bcdDevice
field to figure out special workarounds for a given firmware revision.
This seems to make sense. Therefore this patch converts all gadgets
(except a few) to use the kernel version instead a random 2 or 3 plus
the UDC number. The few that don't report kernel's version are:
- webcam
This one reports always a version 0x10 so allow it to do so in future.
- nokia
This one reports always 0x211. The comment says that this gadget works
only if the UDC supports altsettings so I added a check for this.
- serial
This one reports 0x2400 + UDC number. Since the gadget version is 2.4
this could make sense. Therefore bcdDevice is 0x2400 here.
I also remove various gadget_is_<name> macros which are unused. The
remaining few macros should be moved to feature / bug bitfield.

Some gadgets provide custom entry here. Some may override it with an
etntry that is also created by composite if there was no value sumbitted
at all.
This patch removes all "custom manufacturer" strings which are the same
as these which are created by composite. Then it moves the creation of
the default manufacturer string to usb_composite_overwrite_options() in
case no command line argument has been used and the entry is still an
empty string.
By doing this we get rid of the global variable "composite_manufacturer"
in composite.

The index in usb_string array is defined by the gadget. The gadget can
choose which index entry it assigns for the serial number and which the
product name. The gadget has just to ensure that the descriptor contains
the proper string id which is assigned by composite.
If the composite layer knows the index of the "default" information
which will be overwritten by module parameters, it can be used later to
overwrite it.

After I moved the function from the header file to the c file I see:
| $ size drivers/usb/gadget/gadget_chips.o
| text data bss dec hex filename
| 1048 0 0 1048 418 drivers/usb/gadget/gadget_chips.o
That is almost a KiB which is removed from each user.
As Felipe pointed out, the function / usage is very dumb actually. This is
used for the following reasons:
- epautoconf ep hint (could provide a per-gadget callback)
- miss-features. currently the missing altsetting on pxa's and something
ZLP related on musbhdrc (looks like an optimisation which could be
implemented in musb itself if it is correct)
- unique BCD accross all UDCs. Not sure how important this is.

As it turns out, Sam's comment was better than I initially assumed. This
patch pushes as struct usb_composite_driver data structures into
__refdata section to avoid a section missmatch report from modpost
because the ->bind() can be marked __init. The only downside is that
modpost does not check between ->bind() and other member. However, it is
temporary.

avoids the following section missmatch
|WARNING: drivers/usb/gadget/g_audio.o(.init.text+0x2e7): Section
|mismatch in reference from the function afunc_bind() to the function
|.devexit.text:snd_uac2_remove()
|The function __init afunc_bind() references
|a function __devexit snd_uac2_remove().
|This is often seen when error handling in the init function
|uses functionality in the exit path.
|The fix is often to remove the __devexit annotation of
|snd_uac2_remove() so it may be used outside an exit section.

It was moved to be an argument in 07a18bd716ed5 ("usb gadget: don't
save bind callback in struct usb_composite_driver"). The reason was to
avoid the section missmatch. The warning was shown because ->bind is
marked as __init becuase it is a one time init. The warning can be also
suppresed by whitelisting the variable i.e. rename it to lets say _probe.

Earlier we used to check for ep->ep.desc to figure out if this ep has
already been enabled and if so, abort.
Ido Shayevitz removed the usb_endpoint_descriptor from private udc
structure 5a6506f00 ("usb: gadget: Update at91_udc to use
usb_endpoint_descriptor inside the struct usb_ep") but did not fix up
the ep_enable condition because _now_ the member is always true and we
can't check if this ep is enabled twice.

The driver was converted to the new start/stop interface in f3d8bf34c2
("usb: gadget: at91_udc: convert to new style start/stop interface").
I overlooked that the driver is overwritting the private data which is
used by the composite framework. The udc driver doesn't read it, it is
only written here.

If USB2 host controller probes fine but USB3 does not then we don't
remove the USB controller properly and lock up the system while the HUB
code will try to enumerate the USB2 controller and access memory which
is no longer available in case the dummy_hcd was compiled as a module.
This is a problem since 448b6eb1 ("USB: Make sure to fetch the BOS desc
for roothubs.) if used in USB3 mode because dummy does not provide this
descriptor and explodes later.

Convert a 0 error return code to a negative one, as returned elsewhere in the
function.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@@
identifier ret;
expression e,e1,e2,e3,e4,x;
@@
(
if (\(ret != 0\|ret < 0\) || ...) { ... return ...; }
|
ret = 0
)
... when != ret = e1
*x = \(kmalloc\|kzalloc\|kcalloc\|devm_kzalloc\|ioremap\|ioremap_nocache\|devm_ioremap\|devm_ioremap_nocache\)(...);
... when != x = e2
when != ret = e3
*if (x == NULL || ...)
{
... when != ret = e4
* return ret;
}
// </smpl>

If f_fs.c and u_serial.c are combined together using #include, which has
been a common practice so far, the pr_vdebug macro is defined multiple
times. Define it only once.
