Jonathan writes:

Second set of new driver, functionality and cleanups for IIO in the 4.2 cycle.

Core functionality
* i and q modifiers from quadrature channels.
* IIO_CHAN_INFO_OVERSAMPLING_RATIO added.
* High pass filter attributes added to mirror the existing low pass filter
  ones.

Core cleanups
* Make IIO tools building more cross compiler friendly.
* Substantial rework of the function __iio_update_buffers to greatly simplify
  a hideously evolved function.

New drivers and support
* ACPI0008 ambient light sensor driver. This one has been around a long time to
  will be good to finally get it into mainline.
* Berlin SOC ADC support.
* BMC150 magnetometer.  The accelerometer in the same package has been supported
  for quite some time, so good to have this half as well.
* m62332 DAC driver
* MEMSIC MMC35420 magnetometer.
* ROHM BH1710 and similar ambient light sensors.
* Sensortek STK3310 light sensor.
* Sensortek STK8312 accelerometer.
* Sensortek STK8BA50 accelerometer.
* ti-adc128s052 gains support form the adc122s021 2 channel ADC.

Driver cleanups and functionality.
* Allow various drivers to compile with !GPIOLIB if COMPILE_TEST enabled.
* bmc150 - decouple trigger from buffer to allow other triggers to be used.
* bmg160 - decouple trigger from buffer to allow other triggers to be used.
  Fix a trivial unused field.
* Constify a load of platform_device_id structures.
* inv_mpu6050 - device tree bindings.
* hid-sensors - fix a memory leak during probe if certain errors occur.
* ltr501 - illuminance channel derived (in an non obvious fashion) from the
  intensity channels.
* ltr501 - fix a boundary check on the proximity threshold.
* mlx90614 - drop a pointless return.
* mma8452 - Debugfs register access and fix a bug that had no effect (by
  coincidence)
* ti_am335x_adc - add device tree bindings for sample-delay, open-delay and
  averaging.  The ideal settings for these tend to be board design specific.

* Berlin Analog to Digital Converter (ADC)



The Berlin ADC has 8 channels, with one connected to a temperature sensor.

It is part of the system controller register set. The ADC node should be a

sub-node of the system controller node.



Required properties:

- compatible: must be "marvell,berlin2-adc"

- interrupts: the interrupts for the ADC and the temperature sensor

- interrupt-names: should be "adc" and "tsen"



Example:



adc: adc {

	compatible = "marvell,berlin2-adc";

	interrupt-parent = <&sic>;

	interrupts = <12>, <14>;

	interrupt-names = "adc", "tsen";
