iio: adc: axp288: Drop bogus AXP288_ADC_TS_PIN_CTRL register modifications

For some reason the axp288_adc driver was modifying the
AXP288_ADC_TS_PIN_CTRL register, changing bits 0-1 depending on
whether the GP_ADC channel or another channel was written.

These bits control when a bias current is send to the TS_PIN, the
GP_ADC has its own pin and a separate bit in another register to
control the bias current.

Not only does changing when to enable the TS_PIN bias current
(always or only when sampling) when reading the GP_ADC make no sense
at all, the code is modifying these bits is writing the entire register,
assuming that all the other bits have their default value.

So if the firmware has configured a different bias-current for either
pin, then that change gets clobbered by the write, likewise if the
firmware has set bit 2 to indicate that the battery has no thermal sensor,
this will get clobbered by the write.

This commit fixes all this, by simply removing all writes to the
AXP288_ADC_TS_PIN_CTRL register, they are not needed to read the
GP_ADC pin, and can actually be harmful.

iio: Add gravity sensor support

Gravity sensor is a soft sensor, which derives value from
standard accelerometer device by filtering out the acceleration
which is not caused by gravity.

Gravity sensor provides a three dimensional vector indicating
the direction and magnitude of gravity. Typically, this sensor
is used to determine the device's relative orientation in space.
The units and the coordinate system is the same as the one used by
the acceleration sensor.
When a device is at rest, the output of the gravity sensor should
be identical to that of the accelerometer.

More information can be found in:
http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf

iio: light: add driver for Capella CM3605

This adds a driver for the Capella Microsystems CM3605 Ambient
Light Sensor and proximity sensor. This is a pretty simple entirely
analog device that is interfaced with the target system using
the POUT (proximity out) and AOUT (ambient light out) signals.

The POUT signal is a simple high/low signal that indicates whether
an object is in proximity, most typically used to detect a face
in front of a mobile device. The signal requires that an infrared
LED is mounted next to the device, making IR light reflect off
the object in proximity and triggering the POUT signal. We grab
a GPIO pin to handle the POUT signal as an interrupt line and
register this as an event channel for the sensor.

Since the proximity sensor requires an IR LED, we add a LED trigger
named "cm3605" so that the infrared LED can just associate with
this trigger to be sure it is always on when the proximity sensor
needs it.

The AOUT is an analog voltage between 0 and 1550 mV that indicate
the LUX value in the ambient light: this is orthogonal to the
proximity sensor functionality. Since this analog voltage needs
to be converted into a digital value, the driver grabs an IIO
channel named "aout" associated with the device.

This patch created a combined ALS and proximity sensor driver.
The former supports raw reads of the LUX value and the latter
will generate proximity events.

To integrate this properly with Linux we also add a supply
regulator for the VDD pin (driving both functions) and add device
tree bindings to define the RSET resistor that in turn configures
the luminosity range of the ALS sensor.

Since the sensor needs to be on more or less constantly, we
restrict the power management to system suspend/resume: we
disable the IR LED and disable the regulator for VDD on suspend
and take them back up on resume.

iio: accel: hid-sensor-accel-3d: Add timestamp

Added timestamp channel. With this change, each sample has a timestamp.
This timestamp can be from the sensor hub when present or local kernel
timestamp. HID sensors can send timestamp with input data using usage id
HID_USAGE_SENSOR_TIME_TIMESTAMP. This timestamp value is converted to
nano seconds before pushing this sample to the iio core.

IIO: Change msleep to usleep_range for small msecs

msleep(1~20) may not do what the caller intends, and will often sleep longer.
(~20 ms actual sleep for any value given in the 1~20ms range)
This is not the desired behaviour for many cases like device resume time,
device suspend time, device enable time, data reading time, etc.
Thus, change msleep to usleep_range for precise wakeups.

Merge tag 'iio-for-4.10d' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Fourth set of IIO new device support, features and cleaups for the 4.10 cycle.

Probably the final set before the merge window unless things get significantly
delayed.

New device support
* STM32 ADC core
  - new driver.  Interesting device with up to 3 ADCs with complex triggering
    options that will follow later. Note split into an 'mfd like' core that
    handles the interrupt sharing etc between the various instances present and
    a per ADC section that is instantiated as many times as needed.
  - device tree bindings.

Cleanups and minor fixes
* st_accel
  - inline per sensor data as the defines don't add any meaning and make it
    much harder to check if a given sensor has the right values.
* hid-magnetometer
  - sort out the associations of the associated attributes with the two types.

iio: magnetometer: separate the values of attributes based on their usage type for HID compass sensor

There are 2 usage types (Magnetic Flux and Heading data field) for HID
compass sensor, thus the values of offset, scale, and sensitivity should
be separated according to their respective usage type. The changes made
are as below:
1. Hysteresis: A struct hid_sensor_common rot_attributes is created in
struct magn_3d_state to contain the sensitivity for IIO_ROT.
2. Scale: scale_pre_decml and scale_post_decml are separated for IIO_MAGN
and IIO_ROT.
3. Offset: Same as scale, value_offset is separated for IIO_MAGN and
IIO_ROT.

For sensitivity, HID_USAGE_SENSOR_ORIENT_MAGN_FLUX and
HID_USAGE_SENSOR_ORIENT_MAGN_HEADING are used for sensivitity fields based
