This can be used to distinguish mpu6500. This is a warning rather than
an error because the differences are mostly irrelevant and it's nice to
avoid breaking users with slightly incorrect ACPI/DT.Signed-off-by: Crestez Dan Leonard

The hw_info array was indexed by enum inv_devices chip_type despite the
fact that the enumeration had more members than the array and was
ordered differently.The patch cleans this up and adds explicit chip_types to i2c/spi/acpi
IDs. It also adds some stricter checks inside the driver core.This happened to work so far because the differences between the
supported models are very minor.Signed-off-by: Crestez Dan Leonard

Signed-off-by: Jonathan Cameron -
This adds support for the BMP180 to the bmp280 iio driver.
The BMP180 has already been supported by misc/bmp085 driver but it
doesn't use iio framework. This change adds the kconfig dependency
not to be selected both of them in order to avoid any issues.Signed-off-by: Akinobu Mita

This patch exposes ALSTIM as illuminance_integration_time and ALSPGA as
illuminance_scale.Changing ALSTIM also changes the number of bits available in the data
register. This is handled inside raw value reading because:
* It's very easy to shift a few bits
* It allows SCALE and INT_TIME to be completely independent controls
* Buffer support requires constant scan_type.realbits per-channelSigned-off-by: Crestez Dan Leonard

This is exposed as an output channel with "led" as an extend_name.
Other sensors also have support for controlling an external LED. It's
not clear that simply exposing an undecorated output channel is the
correct approach.Signed-off-by: Crestez Dan Leonard

Expose a rotation matrix to indicate userspace the chip placement with
respect to the overall hardware system. This is needed to adjust
coordinates sampled from a sensor chip when its position deviates from the
main hardware system.Final coordinates computation is delegated to userspace since:
* computation may involve floating point arithmetics ;
* it allows an application to combine adjustments with arbitrary
transformations.This 3 dimentional space rotation matrix is expressed as 3x3 array of
strings to support floating point numbers. It may be retrieved from a
"[_][_]mount_matrix" sysfs attribute file. It is declared into a
device / driver specific DTS property or platform data.Signed-off-by: Gregor Boirie

Some of kernel driver uses the IIO framework to get the sensor
value via ADC or IIO HW driver. The client driver get iio channel
by iio_channel_get_all() and release it by calling
iio_channel_release_all().Add resource managed version (devm_*) of these APIs so that if client
calls the devm_iio_channel_get_all() then it need not to release it
explicitly, it can be done by managed device framework when driver
get un-binded.This reduces the code in error path and also need of .remove callback in
some cases.Signed-off-by: Laxman Dewangan

Some types of ST Sensors can be connected to the same IRQ line
as other peripherals using open drain. Add a device tree binding
and a sensor data property to flip the right bit in the interrupt
control register to enable open drain mode on the INT line.If the line is set to be open drain, also tag on IRQF_SHARED
to the IRQ flags when requesting the interrupt, as the whole
point of using open drain interrupt lines is to share them with
more than one peripheral (wire-or).Cc: devicetree@vger.kernel.org

This makes all ST sensor drivers check that they actually have
new data available for the requested channel(s) before claiming
an IRQ, by reading the status register (which is conveniently
the same for all ST sensors) and check that the channel has new
data before proceeding to read it and fill the buffer.This way sensors can share an interrupt line: it can be flaged
as shared and then the sensor that did not fire will return
NO_IRQ, and the sensor that fired will handle the IRQ and
return IRQ_HANDLED.Cc: Giuseppe Barba

The current buffer read code tries to optimize reads from the
sensor data registers by issuing a single read operation across
all the indata registers.This doesn't work: when the LIS331DL accelerometer sensor is
configured to open drain, active low interrupt mode, this will
just clear the XDA (X-axis data available) bit in the STATUS_REG
register (0x27), while YDA, ZDA and even ZYXDA remain set to 1,
and the internal logic of the sensor holds the DRDY (INT1) line
asserted (the value of the status register is 0xee).If we instead issue one read operation per enabled channel
(X, Y, Z) things start working and we can use open drain and
active low interrupts.Note that a backported patch fixing this issue will be heading
via the fixes branch but changes in this file already in staging-next
will make that patch 'look' rather different. The code in here
is the correct one when that clash hits.Cc: Giuseppe Barba

This is a reimplementation of the old misc device driver for the
ROHM BH1780 ambient light sensor (drivers/misc/bh1780gli.c).Differences from the old driver:
- Uses the IIO framework
- Uses runtime PM to idle the hardware after 5 seconds
- No weird custom power management from userspace
- No homebrewn values in sysfsThis uses the same (undocumented) device tree compatible-string
as the old driver ("rohm,bh1780gli").Cc: Arnd Bergmann
