First set of IIO new device support, features and cleanup for the 4.12 cycle.

Browse source 
Quite a bit of outreachy activity here with a driver from a current intern
 and a number of cleanup patches as part of the next round.
 
 Getting a pull request in early this cycle as it's looking like another large
 cycle for IIO.
 
 New device support
 * adxl345
   - initial device support. Note, once complete support is done the intent
     is to superceded the driver in input/misc.
   - bindings.
   - conversion from i2c direct calls to regmap and driver split.
   - spi support.
 * chromeos light and proximity.
   - new driver.
 * devantech srf04 ultrasonic ranger
   - new driver with device tree bindings.

 Staging graduation
 * isl29028 including copyright notice update to reflect Brian's work.
 * lpc32xx_adc.
 * spear adc. It's not perfect and there are some datasheet disagreements, but
   it works and is good enough to graduate.
 
 New features
 * documentation
   - abi docs for in_proximity_sampling_frequency_available.
   - generalise counting direction ABI docs as a second driver is going to
   use them.

   - Add support for HID_USAGE_SENSOR_HUMAN_PRESENCE if used on a particular
   device.

   - runtime pm.

* Devantech SRF04 ultrasonic range finder
Bit-banging driver using two GPIOs
Required properties:
- compatible: Should be "devantech,srf04"
- trig-gpios: Definition of the GPIO for the triggering (output)
This GPIO is set for about 10 us by the driver to tell the
device it should initiate the measurement cycle.
- echo-gpios: Definition of the GPIO for the echo (input)
This GPIO is set by the device as soon as an ultrasonic
burst is sent out and reset when the first echo is
received.
Thus this GPIO is set while the ultrasonic waves are doing
one round trip.
It needs to be an GPIO which is able to deliver an
interrupt because the time between two interrupts is
measured in the driver.
See Documentation/devicetree/bindings/gpio/gpio.txt for
information on how to specify a consumer gpio.
Example:
srf04@0 {
compatible = "devantech,srf04";
trig-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
echo-gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>;
};
