The ADIS16495 and ADIS16497 are inertial systems that include a triaxis
gyroscope and a triaxis accelerometer. The serial peripheral interface
(SPI) provide a simple interface for data collection and configuration
control. The devices are similar to ADIS16475, ADIS16480, ADIS16485 and
ADIS16488, the main differences are highlighted below:
* The temperature data scale is 0.00565 C/LSB for ADIS16475 and ADIS1648x
devices, while for ADIS1649x 0.0125 C/LSB.
* ADIS1649x devices support different gyroscope measurement ranges which
are dependent on the dash number (-1, -2, -3), see Table 24 in the
ADIS16495 datasheet. However, the ADIS16497 gyroscopes have the same
scale as ADIS16495.
* ADIS16495 devices support the acceleration maximum range of 8g, while
ADIS16497 devices go up to 40g.
* The internal clock for ADIS1649x devices is 4.25 kSPS. The sampling
frequency is calculated by applying a decimation rate which can take a
maximum value of 4250.
* ADIS1649x devices support different default filter frequencies.

When setting the filter frequency, the driver looks into the
adis16480_def_filter_freqs table for the best match. Pass this table to
the chip_info struct since future devices will need to use a different
table.

The adis1648x devices have an internal clock of 2.46 kSPS. The sampling
frequency is calculated by applying a decimation rate which can take the
maximum value of 2047.
Although all adis1648x devices are similar in this regard, devices that
will use this feature will be added in the future.

All supported devices provide internal temperature measurement from -40 C
to +85 C, with +25 C representing value 0x00.
This patch treats the temperature scale in a generic way, similar to the
accelerometer and gyroscope scales. So far, there are no temperature max
scale differences between the supported devices. However, devices that
will make use of this feature will be added in the future.

The FNCTIO_CTRL register provides configuration control for each I/O pin
(DIO1, DIO2, DIO3 and DIO4).
This patch adds the option to configure each DIOx pin as data ready
indicator with positive or negative polarity by reading the 'interrupts'
and 'interrupt-names' properties from the devicetree. The
'interrupt-names' property is optional, if it is not specified, then the
DIO1 pin is used as default data ready signal.
Although the factory default assigns DIO2 as data ready signal, in the
versions previous this patch, DIO1 pin was used. We should leave this
configuration as is, since some devices might be expecting the interrupt
on the wrong physical pin.

If userspace doesn't end the input with a newline (which can easily

# cat device_name
# printf 'eth12' > device_name
# cat device_name
eth12
# printf 'eth3' > device_name
# cat device_name

I highly doubt anybody is relying on this behaviour, so switch to
simply copying the bytes (we've already checked that size is <
IFNAMSIZ) and unconditionally zero-terminate it; of course, we also
still have to strip a trailing newline.

Here are some small USB fixes for 5.1-rc3.
Nothing major at all here, just a small collection of fixes for reported
issues, and potential problems with error handling paths. Also a few
new device ids, as normal.
All of these have been in linux-next with no reported issues.
