Add a new rotation matrix sysfs attribute compliant with IIO core
mounting matrix API.
Matrix is retrieved from "in_anglvel_mount_matrix" and
"in_accel_mount_matrix" sysfs attributes. It is declared into mpu6050 DTS
entry as a "mount-matrix" property.
Old interface is kept for backward userspace compatibility and may be

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).

- Programmable Data Rate Options:
- 15 SPS (16 bits), 60 SPS (14 bits), 240 SPS (12 bits)
The mcp3422 driver also supports the MCP3421 which is a single channel.
So we can support MCP3425 with a little changes to mcp3422 driver.

MAX30100 is an heart rate and pulse oximeter sensor that works using
two LEDS of different wavelengths, and detecting the light reflected
back.
This patchset adds support for both IR and RED LED channels which can
be processed in userspace to determine heart rate and blood oxygen
levels.

Add a property to allow changing the default power-saving mode.
By default, at read raw the chip will activate and provide
one measurent, then it will shut itself down. However, the
chip can also work in "continuous" mode which may be more reliable
but is also more power consuming.

Usual mixed bag, but the big item perhaps in this series is the DMA buffer
support added by Lars-Peter Clausen. It's been in the works for a long time
and it will be interesting to see what hardware support shows up now that
this is available.
New core features + associate cleanup.
* Add generic DMA buffer infrastructure
* Add a DMAengine framework based buffer
Also associated minor changes.
- Set the device buffer watermark based on the minimum watermark for all
attached buffers rather than just the 'primary' one.
- iio_buffer_init - only set the watermark default if one hasn't already
been provided. This allows simple support for devices with a fixed
watermark.
- read only attribute for watermark on fixed watermark devices.
- add explicit buffer enable/disable callbacks to allow the buffer to
do more than trivial actions when it is being turned on and off.
* IIO_VAL_INT support in write_raw_get_fmt function.
New device support
* Freescale MMA7455/7456L accelerometers
* Memsic MXC6255XC accelerometer
* ST lis2dh12 accelerometer
* TI ADS8688 ADC
* TI Palamas (twl6035/7) gpadc
New driver features
* mma8452
- support either of the available interrupt pins to cope with the case
where board layout has lead to a particular one being connected.
Staging graduation
* Dummy driver
- this driver acts as both an example and a test device for those with
out hardware to develop userspace code against.
Cleanups and minor bits and bobs.
* treewide
- Sort out the ordering of iio_device_register/unregister vs runtime
pm function calls so that it's all nice and consistent and not race
prone.
- Check sscanf return values. None of the cases will actually happen as
the strings are supplied internally, but best to be consistent on this.
* ad7780
- switch over to the gpio descriptor interface and remove the now unused
platform data which gets rid of a header entirely.
* ad7793
- drop a pointless else statement.
* at91_adc
- Swap kmalloc_array in for a kmalloc doing the same job.
* dummy
- get rid of some commented out lines that snuck in during the move of

The Microchip Analog to Digital Converter (ADC) Device Tree binding
documents compatible strings with no vendor prefix. Since it should
compatible strings with also a vendor, add these to the binding doc
and mark the old ones as deprecated.
The driver says that the device is from Microchip Technology which
is listed in Documentation/devicetree/bindings/vendor-prefixes.txt
so use the documented prefix.

This change is important in order for everyone to be easily able to use the
driver for one of the supported accelerometer chips!
Until now, the driver blindly assumed that the INT1 interrupt line is wired
on a user's board. But these devices have 2 interrupt lines and can route
their interrupt sources to one of them. Now, if "INT2" is found and matches
i2c_client->irq, INT2 will be used.
The chip's default actually is INT2, which is why probably many boards will
have it wired and can make use of this.
Of course, this also falls back to assuming INT1, so for existing users
nothing will break. The new functionality is described in the bindings doc.

The bma180 / bma250 accelerometers share a driver (at least under Linux),
so it makes sense to also have their bindings info in a single .txt.
This commit extends the bma180 bindings with bma250 bindings, specifically
it specifies how the 2 seperate interrupts the bma250 has must be listed
in devicetree. The existing bma180 driver is already fully compatible
with the specified bindings.
