Pull staging driver update from Greg KH:
"Here's the big drivers/staging/ update for 3.13-rc1.
Nothing major here, just a _ton_ of fixes and cleanups, mostly driven
by the new round of OPW applicants, but also there are lots of other
people doing staging tree cleanups these days in order to help get the
drivers into mergable shape.
We also merge, and then revert, the ktap code, as Ingo and the other
perf/ftrace developers feel it should go into the "real" part of the
kernel with only a bit more work, so no need to put it in staging for
now.
All of this has been in linux-next for a while with no reported
issues"

Felipe writes:
usb: patches for v3.13
Final conversions to configfs for mass storage, acm_ms, and
multi gadgets.
MUSB should now work out of the box on AM335x-based boards
(beagle bone white and black) with DMA thanks to Sebastian's
work.
We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/
by selecting CONFIG_USB_GADGET_VERBOSE.
s3c-hsotg got quite a few non-critical fixes but also learned
a few new tricks (isochronous transfers, multi count support).
The Marvel USB3 Controller driver got a memory leak fix.
devm_usb_get_phy() learned not to return NULL, ever.
Other than these patches, we have the usual set of cleanups
ranging from removal of unnecessary *_set_drvdata() to using
SIMPLE_DEV_PM_OPS.

"Sorry I let so much accumulate, I was in Buffalo and wanted a few
things to cook in my tree for a while before sending to you. Anyways,
it's a lot of little things as usual at this stage in the game"

Carpenter.

Dumazet.

Kleine-Budde.
11) Fix permission checks in sysctls to use current_euid() instead of

Ghorbel.
16) Fix typo in fq_change(), we were assigning "initial quantum" to
"quantum". From Eric Dumazet.
17) Set a more appropriate sk_pacing_rate for non-TCP sockets, otherwise
FQ packet scheduler does not pace those flows properly. Also from
Eric Dumazet.
18) rtlwifi miscalculates packet pointers, from Mark Cave-Ayland.
19) l2tp_xmit_skb() can be called from process context, not just softirq

the driver during TX queueing. From Eric Dumazet.

raw sockets. We mix up the users requested destination address with
the routes assigned nexthop/gateway. From Julian Anastasov and
Simon Horman.

AM43x has 224 interrupts and 7 banks, make it as maximum values. Keep
default values as earlier, if am43x is detected, update interrupts and
banks accordingly.
Also AM43x has only one cpu, ensure that clearing bitmask at wakeupgen
is done only for the single existing cpu, existing code assumes that
there are two cpu's.
If bitmask is cleared in wakeupgen for the nonexistent second cpu,
an imprecise abort happens as soon as Kernel switches to user space.

AT91 ADC hardware integrate touch screen support. So this patch add touch
screen support for at91 adc iio driver.
To enable touch screen support in adc, you need to add the dt parameters:
1. which type of touch are used? (4 or 5 wires), sample period time.
2. correct pressure detect threshold value.
In the meantime, since touch screen will use a interal period trigger of adc,
so it is conflict to other hardware triggers. Driver will disable the hardware
trigger support if touch screen is enabled.
This driver has been tested in AT91SAM9X5-EK and SAMA5D3x-EK.

DPHYs so we can remove now unused code at arch/arm/plat-samsung.
In case there is any board file for S5PV210 platforms using MIPI
CSIS/DSIM (not any upstream currently) it should use the generic
PHY API to bind the PHYs to respective PHY consumer drivers and
a platform device for the PHY provider should be defined.

and trats boards
Exynos cpufreq drivers does not support device tree based regulator
lookup, so it can get the VDD ARM regulator only by its name. To get
cpufreq working for now, this patch works this around by renaming the
regulator in board dts files to vdd_arm, which is the name expected by
the driver.
This fixes a regression introduced by dropping support of board file
based bootup of Exynos 4210 boards that rendered cpufreq inoperable on
Trats and Origen boards.

This fixes a long-standing Integrator/CP regression from
commit 870e2928cf3368ca9b06bc925d0027b0a56bcd8e
"ARM: integrator-cp: convert use CLKSRC_OF for timer init"
When this code was introduced, the both aliases pointing the
system to use timer1 as primary (clocksource) and timer2
as secondary (clockevent) was ignored, and the system would
simply use the first two timers found as clocksource and
clockevent.
However this made the system timeline accelerate by a
factor x25, as it turns out that the way the clocking
actually works (totally undocumented and found after some
trial-and-error) is that timer0 runs @ 25MHz and timer1
and timer2 runs @ 1MHz. Presumably this divider setting
is a boot-on default and configurable albeit the way to
configure it is not documented.
So as a quick fix to the problem, let's mark timer0 as
disabled, so the code will chose timer1 and timer2 as it
used to.
This also deletes the two aliases for the primary and
secondary timer as they have been superceded by the
auto-selection

In ftrace_syscall_enter(),
syscall_get_arguments(..., 0, n, ...)
if (i == 0) { <handle ORIG_r0> ...; n--;}
memcpy(..., n * sizeof(args[0]));
If 'number of arguments(n)' is zero and 'argument index(i)' is also zero in
syscall_get_arguments(), none of arguments should be copied by memcpy().
Otherwise 'n--' can be a big positive number and unexpected amount of data
will be copied. Tracing system calls which take no argument, say sync(void),
may hit this case and eventually make the system corrupted.
This patch fixes the issue both in syscall_get_arguments() and
syscall_set_arguments().

THis is because the Exynos u-boot, for example on the Chromebooks, doesn't set
up the CNTFRQ register as expected by arch_timer. Instead, we have to specify
the frequency in the device tree like this.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:
Few fixes for omap3 related hangs and errors that people have
noticed now that people are actually using the device tree
based booting for omap3.
Also one regression fix for timer compile for dra7xx when
omap5 is not selected, and a LED regression fix for n900.

File drivers/leds/leds-lp55xx-common.c refuse to change led_current sysfs
attribute if value is higher than max_current specified in board file. By default
global C variables are zero, so changing always failed. This patch adding missing
max_current and setting it to max safe value 100 (10 mA).
It is unclear which commit exactly caused this regression as the lp5523
driver was broken and was hiding the platform data breakage. Now
the driver is fixed so this should be fixed as well.

This patch adds a omap1510_fpga_init_irq() inline dummy implementations
in arch/arm/mach-omap1/common.h. Without this patch,build system can
lead to issues. This was discovered during randconfig testing,in which
other than CONFIG_ARCH_OMAP15XX was enabled the leading to the following

The wake-up interrupt bit is available on omap3/4/5 processors
unlike what we claim. Without fixing it we cannot use it on
omap3 and the system configured for wake-up events will just
hang on wake-up.

SoC family definitions at the moment are reactive to board needs
as a result, beagle-xm would matchup with ti,omap3 which invokes
omap3430_init_early instead of omap3630_init_early. Obviously, this is
the wrong behavior.
With clock node dts conversion, we get the following warnings before
system hangs as a result and 3630 based platforms fails to boot
(uart4 clocks are only present in OMAP3630 and not present in
OMAP3430):
...
omap_hwmod: uart4: cannot clk_get main_clk uart4_fck
omap_hwmod: uart4: cannot _init_clocks

So, add specific compatiblity for 3630 to allow match for Beagle-XM
