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.

udelay is impelmented using a busy-wait loop and consumes CPU cycles

First set of IIO new device support, features and cleanup for the 4.12 cycle.
Quite a bit of outreachy activity here with a driver from a current intern
and a number of cleanup patches as part of the next round.
Getting a pull request in early this cycle as it's looking like another large
cycle for IIO.

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.
