Since the code for multicast filtering has been dropped, the function
hif_set_data_filtering() is only called to disable multicast filtering.
In fact, the multicast filtering is already disabled by default. So,
this function is useless and can be dropped.
The device allows to filter multicast frames. The driver has the
necessary code to take advantage of this feature. However, some bugs
has been reported on this feature. So, it was temporary disabled.
Finally, the things work well as-is for more than one year now. So there
is no plan to enable this feature in near future.
The Secure Link (slk) feature allows to encrypt (and authenticate) the
traffic between the host and the device. The official implementation of
this feature relies on mbedTLS. For that reason, this implementation is
not included in the current driver. To be included, the implementation
has to rely on kernel crypto API instead of mbedTLS.
So, for now, the driver contained stub functions waiting for the new
implementation based on kernel crypto API.
This new implementation represent a bunch of work and it is unlikely to
be done in near future. Moreover, we strongly dislike to maintain
useless code. So, drop all the code related to secure link.
Whoever wants to implement secure link should revert this patch before
starting to work on it.
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: bma220: Drop ACPI_PTR() and accompanying ifdeffery
The driver is quite likely used only on ACPI based platforms and
rarely build with CONFIG_ACPI=n. Even though, the few dozens of bytes
is better than ugly ifdeffery and inclusion of heavy header.
As a result, replace acpi.h with mod_devicetable.h.
Drops the deprecated compatibles without the vendor name.
Whilst the driver continues to support these for old dt blobs,
any dt bindings that are actuallly verified against this document should
be fixed to add the vendor name.
Added the #io-channel-cells property to allow for consumers.
iio: buffer-dmaengine: adjust `bytes_used` with residue info
A transfer may fall shorter than the bytes in the block.
This information is available in the residue from the DMA engine, so we can
compute actual `bytes_used` with that by subtracting the residue.
Simple binding so easy to convert.
Dropped the stated value of maximum spi bus frequency as it does
not seem to correspond to the datasheet. The value of 200kHz
is the max sampling frequency of the ADC, not the clock frequency of
the SPI bus.
Added #io-channel-cells to allow use as a provider of channels to
other devices via the consumer binding.
Simple conversion for this ADC driver. Note that I haven't put
limits on the spi-max-sampling-frequency because the adc161s626
doesn't state one clearly defined value.
Added the #io-channel-cells property to allow for consumers.

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: Some stylefixing leftovers
There is some inconsistency and whitespace cleanup performed in this
patch. It was done on top of my other patches, but I can rebase to head
of the togreg branch if it would go in sooner.
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.
