Merge tag 'iio-for-v4.2a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First round of new drivers, functionality and cleanups for the 4.2 cycle

New drivers / device support
* st sensors driver, lsm303dlh magnetometer support.
* ltr501 - support ltr301 and ltr559 chips.

New functionality
* IIO_CHAN_INFO_CALIBEMISSIVITY for thermopile sensors.
* kxcjk1013 - make driver operational with external trigger.
* Add iio targets to the tools Makefile.

Cleanups
* st sensors - more helpful error message if device id wrong or irq request
  fails, explicitly make the Block Data Update optional rather
  than relying on writes to address 0 not doing anything, make interrupt
  support optional (Not always wired, and not all devices actually have
  an interrupt line.)
* kxcjk-1013 white space additions for readability, add the KXCJ9000 ACPI
  id as seen in the wild.
* sx9500 - GPIO reset support, refactor the GPIO interrupt code, add power
  management, optimize power usage by powering down when possible, rename
  the gpio interrupt pin to be more useful, trivial return path simplification,
  trivial formatting fixes.
* isl29018 -  move towards ABI compliance with a view to moving this driver
  out of staging, add some brackets to ensure code works as expected.  Note
  there is no actual bug as the condition being tested is always true
  (with current devices).
* ltr501 - add regmap support to get caching etc for later patches,
  fix a parameter sanity check that always fails (bug introduced
  earlier in this series), ACPI enumeration support,
  interrupt rate control support, interrupt support in general and
  integration time control support, code alignment cleanups.
* mma9553 - a number of little cleanups following a review from Hartmut
  after I'd already applied the original driver patch.
* tmp006 - prefix some defines with TMP006 for consistency.
* tsl4531 - cleanup some wrong prefixes, presumably from copy and paste.
* mlx90614 - check for errors in read values, add power management,
  add emissivity setting, add device tree binding documentation,
  fix a duplicate const warning.
* ti_am335x_adc - refactor the DT parsing into a separate function.

		The emissivity ratio of the surface in the field of view of the

* Melexis MLX90614 contactless IR temperature sensor



http://melexis.com/Infrared-Thermometer-Sensors/Infrared-Thermometer-Sensors/MLX90614-615.aspx



Required properties:



  - compatible: should be "melexis,mlx90614"

  - reg: the I2C address of the sensor



Optional properties:



  - wakeup-gpios: device tree identifier of the GPIO connected to the SDA line

      to hold low in order to wake up the device.  In normal operation, the

      GPIO is set as input and will not interfere in I2C communication.  There

      is no need for a GPIO driving the SCL line.  If no GPIO is given, power

      management is disabled.



Example:



mlx90614@5a {

	compatible = "melexis,mlx90614";

	reg = <0x5a>;

	wakeup-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;

};
