The analog support in the cx23885 driver was completely broken for the
HVR-1250. Add the necessary code.
Note that this only implements analog for the composite and s-video
inputs. The tuner input continues to be non-functional due to a lack of
analog support in the mt2131 driver.

The location of the vsrc/hsrc registers moved in the cx23888, causing
the s_mbus call to fail prematurely indicating that "720x480 is not a
valid size". The function bailed out before many pertinent registers
were set related to the scaler (causing unexpected results in video
rendering when doing raw video capture).
Use the correct registers for the cx23888.

Commit 7a6f6c29d264cdd2fe0eb3d923217eed5f0ad134 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

Sometimes it doesn't make any sense for a node to have an address.
In this case device lookup will always be unsuccessful because we
currently assume every node will have a reg property. This patch
changes the semantics so that the resource address and the lookup
address will only be compared if one exists.
Things like AUXDATA() rely on of_dev_lookup to return the lookup
entry of a particular device in order to do things like apply
platform_data to a device. However, this is currently broken for
nodes which do not have a reg property, meaning that platform_data
can not be passed in those cases.

When using urb->transfer_buffer we need to allocate physical contiguous buffers
for the entire transfer, which is pretty much guaranteed to fail with large
transfers.
Currently userspace works around this by breaking large transfers into multiple
urbs. For large bulk transfers this leads to all kind of complications.
This patch makes it possible for userspace to reliable submit large bulk
transfers to scatter-gather capable host controllers in one go, by using a
scatterlist to break the transfer up in managable chunks.

There are a few (new) usbdevfs capabilities which an application cannot
discover in any other way then checking the kernel version. There are 3
problems with this:
1) It is just not very pretty.
2) Given the tendency of enterprise distros to backport stuff it is not
reliable.
3) As discussed in length on the mailinglist, USBDEVFS_URB_BULK_CONTINUATION
does not work as it should when combined with USBDEVFS_URB_SHORT_NOT_OK
(which is its intended use) on devices attached to an XHCI controller.
So the availability of these features can be host controller dependent,
making depending on them based on the kernel version not a good idea.
This patch besides adding the new ioctl also adds flags for the following
existing capabilities:
USBDEVFS_CAP_ZERO_PACKET, available since 2.6.31
USBDEVFS_CAP_BULK_CONTINUATION, available since 2.6.32, except for XHCI
USBDEVFS_CAP_NO_PACKET_SIZE_LIM, available since 3.3
Note that this patch only does not advertise the USBDEVFS_URB_BULK_CONTINUATION
cap for XHCI controllers, bulk transfers with this flag set will still be
accepted when submitted to XHCI controllers.
Returning -EINVAL for them would break existing apps, and in most cases the
troublesome scenario wrt USBDEVFS_URB_SHORT_NOT_OK urbs on XHCI controllers
will never get hit, so this would break working use cases.
The disadvantage of not returning -EINVAL is that cases were it is causing
real trouble may go undetected / the cause of the trouble may be unclear,
but this is the best we can do.

We don't need to open code the divide function, just use div_u64 that
already exists and do the same job. While this is a straightforward
clean up, there is more to that, the real motivation for this.
While building on a cross compiling environment in armel, using gcc
4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5), I was getting the following build
error:
ERROR: "__aeabi_uldivmod" [drivers/mtd/nand/nandsim.ko] undefined!
After investigating with objdump and hand built assembly version
generated with the compiler, I narrowed __aeabi_uldivmod as being
generated from the divide function. When nandsim.c is built with
-fno-inline-functions-called-once, that happens when
CONFIG_DEBUG_SECTION_MISMATCH is enabled, the do_div optimization in
arch/arm/include/asm/div64.h doesn't work as expected with the open
coded divide function: even if the do_div we are using doesn't have a
constant divisor, the compiler still includes the else parts of the
optimized do_div macro, and translates the divisions there to use
__aeabi_uldivmod, instead of only calling __do_div_asm -> __do_div64 and
optimizing/removing everything else out.
So to reproduce, gcc 4.6 plus CONFIG_DEBUG_SECTION_MISMATCH=y and
CONFIG_MTD_NAND_NANDSIM=m should do it, building on armel.
After this change, the compiler does the intended thing even with
-fno-inline-functions-called-once, and optimizes out as expected the
constant handling in the optimized do_div on arm. As this also avoids a
build issue, I'm marking for Stable, as I think is applicable for this
case.

lots of changes for the dwc3 driver which will make
the driver a lot more stable and some changes which

The bulk of changes is related to mis-defined macros
which were never used before, some fixes to error path
which e.g. prevent the driver from initiating two
transfer on ep0out in case of stall, some fixes to
request dequeueing and the End Transfer Command.
We have some changes to U1/U2 handling where we were
enabling those transtions at the wrong spot (though
we haven't seen a problem from that as of today).
A few patches will make it easier to add support for
newer releases of the core by adding definitions for
new registers and changing the code to act accordingly
when certain revisions are detected.
There's also the usual comestic changes to make the
driver easier to maintain and make it easier for new-
comers to understand the driver. Also one patch fixing
a double inclusion of a header.

Merge tag 'dwc3-for-v3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
usb: dwc3: patches for v3.6 merge window
lots of changes for the dwc3 driver which will make
the driver a lot more stable and some changes which
are just cosmetic.
The bulk of changes is related to mis-defined macros
which were never used before, some fixes to error path
which e.g. prevent the driver from initiating two
transfer on ep0out in case of stall, some fixes to
request dequeueing and the End Transfer Command.
We have some changes to U1/U2 handling where we were
enabling those transtions at the wrong spot (though
we haven't seen a problem from that as of today).
A few patches will make it easier to add support for
newer releases of the core by adding definitions for
new registers and changing the code to act accordingly
when certain revisions are detected.
There's also the usual comestic changes to make the
driver easier to maintain and make it easier for new-
comers to understand the driver. Also one patch fixing
a double inclusion of a header.
This is quite a big pull request and contains patches
all over the place.
omap_udc is now a bit cleaner after removing omap2 support,
fixing some checkpatch.pl warnings and errors, switching over
to generic map/unmap routines and preventing a NULL pointer
de-reference.
s3c-hsotg has been switched over to devm_* API, got some
locking fixes and improvements and it also got an implementation
for the pullup() method.
the mass storage gadgets changed default value of the removable
parameter, dropped some unused options and made "file" and "ro"
module_parameters read-only in some cases.
ffs function got support for HID descriptor.
Some UDCs have been converted to clk_prepare_enable() and
clk_disable_unprepare().
Marvell now got support for its USB3 controller in mainline
after introducing its mv_u3d_core.c driver.

Just two patches here:
First we have a fix to disable DMA in case DMA channel
request fails.
Second, there's a fix for situations where the user
kills musb (by rmmod or any other means) while a
transfer is on the fly. In such cases, we could be
led into a NULL pointer dereference due to endpoint
being disabled and endpoint descriptor being NULL.

Pull leds fix from Bryan Wu:
"Fix for heartbeat led trigger driver"
* 'fixes-for-3.5' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/linux-leds:
leds: heartbeat: fix bug on panic
Pull DT fixes from Rob Herring:
"Mainly some documentation updates and 2 fixes:
- An export symbol fix for of_platform_populate from Stephen W.
- A fix for the order compatible entries are matched to ensure the
first compatible string is matched when there are multiple matches."
Normally these would go through Grant Likely (thus the "fixes-for-grant"
branch name), but Grant is in the middle of moving to Scotland, and is
practically offline until sometime in August. So pull directly from Rob.

The chained handler was set for the platform device with id == 0.
When the gpio devices are instantiated by a device tree, all have id ==
-1 and so the handler was unset resulting in unusable gpio irqs on
i.MX21 and i.MX27 (when using oftree).
