staging: wfx: simplify hif_set_association_mode()

The file hif_tx_mib.c expects to contain functions that format messages
for the hardware. It is unexpected to find function that manipulate
RCU and structures from mac80211.

Keep hif_set_association_mode() with the code necessary for message
formatting and relocate the smart part in wfx_join_finalize().

staging: tegra-vde: fix common struct sg_table related issues

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function
returns the number of the created entries in the DMA address space.
However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and
dma_unmap_sg must be called with the original number of the entries
passed to the dma_map_sg().

struct sg_table is a common structure used for describing a non-contiguous
memory buffer, used commonly in the DRM and graphics subsystems. It
consists of a scatterlist with memory pages and DMA addresses (sgl entry),
as well as the number of scatterlist entries: CPU pages (orig_nents entry)
and DMA mapped pages (nents entry).

It turned out that it was a common mistake to misuse nents and orig_nents
entries, calling DMA-mapping functions with a wrong number of entries or
ignoring the number of mapped entries returned by the dma_map_sg()
function.

To avoid such issues, lets use a common dma-mapping wrappers operating
directly on the struct sg_table objects and use scatterlist page
iterators where possible. This, almost always, hides references to the
nents and orig_nents entries, making the code robust, easier to follow
and copy/paste safe.

iio: accel: adxl372: Add support for FIFO peak mode

By default, if all three channels (x, y, z) are enabled, sample sets of
concurrent 3-axis data is stored in the FIFO. This patch adds the option
to configure the FIFO to store peak acceleration (x, y and z) of every
over-threshold event. When pushing to iio buffer we push only enabled
axis data.

Currently the driver configures adxl372 to work in loop mode.
The inactivity and activity timings  decide how fast the chip
will loop through the awake and waiting states and the
thresholds on x,y,z axis decide when activity or inactivity
will be detected.

This patch adds standard events sysfs entries for the inactivity
and activity timings: thresh_falling_period/thresh_rising_period
and for the in_accel_x_thresh_falling/rising_value.

iio:temperature:mlx90632: Adding extended calibration option

For some time the market wants medical grade accuracy in medical range,
while still retaining the declared accuracy outside of the medical range
within the same sensor. That is why we created extended calibration
which is automatically switched to when object temperature is too high.

This patch also introduces the object_ambient_temperature variable which
is needed for more accurate calculation of the object infra-red
footprint as sensor's ambient temperature might be totally different
than what the ambient temperature is at object and that is why we can
have some more errors which can be eliminated. Currently this temperature
is fixed at 25, but the interface to adjust it by user (with external
sensor or just IR measurement of the other object which acts as ambient),
will be introduced in another commit.

iio:adc:ti-adc108s102: Drop CONFIG_OF and of_match_ptr protections

I'm trying to clean this (now) anti-pattern out of IIO to avoid
cut and paste into new drivers.

Also add an include of mod_devicetable.h as the driver directly uses
struct of_device_id which is defined in there.

iio:adc:ti-adc128s052: drop of_match_ptr protection

There is no real advantage in having these protections and
for parts that do not have an explicit ACPI ID, it prevents the
use of PRP0001. I'm trying to clear this out of IIO in general
to avoid copying in new drivers.

Include mod_devicetable.h as we are using of_device_id in here so
including that header is best practice.

iio:adc:bcm_iproc: Drop of_match_ptr protection and switch to mod_devicetable.h

This driver cannot be instantiated from ACPI due to it's use of
syscon_regmap_lookup_by_phandle() but in the interests of clearing
this anti pattern out of IIO, let us switch to an explicit
check in Kconfig and remove the protections on the of_match_table
The switch of header is because we only use of_device_id
in here and that is defined in mod_devicetable.h not of.h.

iio-trig-hrtimer or iio-trig-sysfs is required.

The sensor supports single and continuous measurement modes. The latter
is not used by design as this would require tight timing synchronization
between hardware and driver without much benefit.
