Pull ARM SoC platform updates from Olof Johansson:
"SoC updates, mostly refactorings and cleanups of old legacy platforms.
Major themes this release:
- Conversion of ixp4xx to a modern platform (drivers, DT, bindings)
- Moving some of the ep93xx headers around to get it closer to
multiplatform enabled.
- Cleanups of Davinci
This also contains a few patches that were queued up as fixes before
5.1 but I didn't get sent in before release"

Add initial support for the AT42QT1050 (QT1050) device. The device
supports up to five input keys, dependent on the mode. Since it adds only
the initial support, the "1 to 4 keys plus Guard Channel" mode isn't
supported.

Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af34
("fs: stream_open - opener for stream-like files so that read and write
can run simultaneously without deadlock"), search and convert to
stream_open all in-kernel nonseekable_open users for which read and
write actually do not depend on ppos and where there is no other methods
in file_operations which assume @offset access.
I've verified each generated change manually - that it is correct to convert -
and each other nonseekable_open instance left - that it is either not correct
to convert there, or that it is not converted due to current stream_open.cocci
limitations. The script also does not convert files that should be valid to
convert, but that currently have .llseek = noop_llseek or generic_file_llseek
for unknown reason despite file being opened with nonseekable_open (e.g.
drivers/input/mousedev.c)
Among cases converted 14 were potentially vulnerable to read vs write deadlock
(see details in 10dce8af34):

One can also recheck/review the patch via generating it with explanation comments included via
$ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci SPFLAGS="-D explain"
(*) This second group also contains cases with read/write deadlocks that
stream_open.cocci don't yet detect, but which are still valid to convert to
stream_open since ppos is not used. For example drivers/pci/switch/switchtec.c
calls wait_for_completion_interruptible() in its .read, but stream_open.cocci
currently detects only "wait_event*" as blocking.

This patch adds support for the Azoteq IQS550/572/525 family of
trackpad/touchscreen controllers.
The driver has been tested with an IQS550EV02 evaluation board. A
demonstration of the driver's capabilities is available here:

This modernizes the IXP4xx platform and adds initial Device Tree
Support. We migrate to MULTI_IRQ_HANDLER, bumps the IRQs to
offset 16, converts to SPARSE_IRQ, then we add proper subsystem
drivers in each subsystem for irqchip, GPIO and clocksource and
switch over to using these new drivers.
Next we modernize the NPE and QMGR drivers and push them down
into drivers/soc.
This has been tested on the IXP4xx NSLU2 and the Gateworks
GW2358-4.

ep93xx does not have a proper pinctrl driver, but does things
ad-hoc through mach/platform.h, which is also used for setting
up the boards.
To avoid using mach/*.h headers completely, let's move the interfaces
into include/linux/soc/. This is far from great, but gets the job
done here, without the need for a proper pinctrl driver.

We can communicate the clock rate using platform data rather than setting
a flag to use a particular value in the driver, which is cleaner and
avoids the dependency.
No platform in the kernel currently defines the ep93xx keypad device
structure, so this is a rather pointless excercise. Any out of tree
users are probably dead now, but if not, they have to change their
platform code to match the new platform_data structure.

Pull input fixes from Dmitry Torokhov:
"Just a couple of fixups for Synaptics RMI4 driver and allowing
snvs_pwrkey to be selected on more boards"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
Input: synaptics-rmi4 - write config register values to the right offset
Input: synaptics-rmi4 - fix possible double free
Input: snvs_pwrkey - make it depend on ARCH_MXC
Currently any changed config register values don't take effect, as the
function to write them back is called with the wrong register offset.

sensors and F11)

The driver doesn't set an initial video format until s_input is called:
$ v4l2-ctl -d /dev/v4l-touch0 --get-input
Video input : 0 (Normalized 16-Bit Image: ok)
$ v4l2-ctl -d /dev/v4l-touch0 --get-fmt-video
Width/Height : 0/0
Pixel Format : ''
[...]
$ v4l2-ctl -d /dev/v4l-touch0 --set-input 0
Video input set to 0 (Normalized 16-Bit Image: Touch, ok)
$ v4l2-ctl -d /dev/v4l-touch0 --get-fmt-video
Width/Height : 71/40
Pixel Format : 'TD16'
[...]
To fix this, initialize the video format to input 0 during probe.

The SNVS power key is not only used on i.MX6SX and i.MX7D, it is also
used by i.MX6UL and NXP's latest ARMv8 based i.MX8M series SOC. So
update the config dependency to use ARCH_MXC, and add the COMPILE_TEST
too.
