staging: iio: ad9832: replace mlock with driver private lock
The IIO subsystem is redefining iio_dev->mlock to be used by
the IIO core only for protecting device operating mode changes.
ie. Changes between INDIO_DIRECT_MODE, INDIO_BUFFER_* modes.
In this driver, mlock was being used to protect hardware state
changes. Replace it with a lock in the devices global data.

iio: adc: add support for Allwinner SoCs ADC
The Allwinner SoCs all have an ADC that can also act as a touchscreen
controller and a thermal sensor. This patch adds the ADC driver which is
based on the MFD for the same SoCs ADC.
This also registers the thermal adc channel in the iio map array so
iio_hwmon could use it without modifying the Device Tree. This registers
the driver in the thermal framework.
The thermal sensor requires the IP to be in touchscreen mode to return
correct values. Therefore, if the user is continuously reading the ADC
channel(s), the thermal framework in which the thermal sensor is
registered will switch the IP in touchscreen mode to get a temperature
value and requires a delay of 100ms (because of the mode switching),
then the ADC will switch back to ADC mode and requires also a delay of
100ms. If the ADC readings are critical to user and the SoC temperature
is not, this driver is capable of not registering the thermal sensor in
the thermal framework and thus, "quicken" the ADC readings.
This driver probes on three different platform_device_id to take into
account slight differences (registers bit and temperature computation)
between Allwinner SoCs ADCs.

MAINTAINERS: drop broken reference to i2c/trivial-devices
Due to RST rework, the reference to i2c/trivial-devices was changed, but the
result is broken. However, let's just drop the whole reference, since it
doesn't make sense in the first place to reference this "global" file
for a single driver.

The camera code has an explicit cache flush operation
which is not portable. Now that vc04_services is using portable
DMA APIs that already do the cache flushing, explicit flushes
should no longer be needed.
The one call to __cpuc_flush_dcache_area has been removed.
Testing:
The offical V2 camera for the RPI was tested on a RPI 3
running in 32 bit mode(armhf). The cheese application
and ffmpeg was used to view and stream video from the
camera. Nothing new seems to be broken without the
cache flushing.

The structure is used as an argument to module_param macro. This
macro calls a bunch of other macros and finally assigns the instance
of the kernel_param_ops structure to the const struct
kernel_param_ops* field of a variable of type kernel_param. Hence,
const can be added to the structure.

staging/atomisp: Add support for the Intel IPU v2
This patch adds support for the Intel IPU v2 as found on Android and IoT
Baytrail-T and Baytrail-CR platforms (those with the IPU PCI mapped). You
will also need the firmware files from your device (Android usually puts
them into /etc) - or you can find them in the downloadable restore/upgrade
kits if you blew them away for some reason.
It may be possible to extend the driver to handle the BYT/T windows
platforms such as the ASUS T100TA. These platforms don't expose the IPU via
the PCI interface but via ACPI buried in the GPU description and with the
camera information somewhere unknown so would need a platform driver
interface adding to the codebase *IFF* the firmware works on such devices.
To get good results you also need a suitable support library such as
libxcam. The camera is intended to be driven from Android so it has a lot of
features that many desktop apps don't fully spport.
In theory all the pieces are there to build it with -DISP2401 and some
differing files to get CherryTrail/T support, but unifying the drivers
properlly is a work in progress.
The IPU driver represents the work of a lot of people within Intel over many
years. It's historical goal was portability rather than Linux upstream. Any
queries about the upstream aimed driver should be sent to me not to the
original authors.
