NOTE:
- Driver exposes 4 channels. One IIO_LIGHT channel providing the
calculated lux values based on measured data from diodes #0 and
#1. In addition, 3 IIO_INTENSITY channels are emitting the raw
register data from all diodes for more intense user-space
computations.
- Sensor has GAIN values that can be adjusted from 1x to 4096x.
- Sensor has adjustible measurement times of 5, 55, 100, 200 and
400 mS. Driver does not support 5 mS which has special
limitations.
- Driver exposes standard 'scale' adjustment which is
implemented by:
1) Trying to adjust only the GAIN
2) If GAIN adjustment alone can't provide requested
scale, adjusting both the time and the gain is
attempted.
- Driver exposes writable INT_TIME property that can be used
for adjusting the measurement time. Time adjustment will also
cause the driver to try to adjust the GAIN so that the
overall scale is kept as close to the original as possible.

iio: light: Add a driver for Sharp GP2AP002x00F

This driver handles two different Sharp sensors that have been
proposed for merging to the mainline kernel over the years, and
already has a limited proximity-only driver in the input
subsystem.

These components are completely different from the confusingly
similarly named Sharp GP2AP020A00F, for which we have a driver
in drivers/iio/light/gp2ap020a00f.c

The two components GP2AP002A00F and GP2AP002S00F are
distinctively different but similar: they share the same set of
registers but differ slightly in the I2C protocol.

Instead of the approach by the previous input driver, we create
a combined IIO proximity and light sensor driver.

The plan is to merge this driver and delete the input driver.

The pieces for the driver are picked all over the place after
researching and grepping through a few different vendor trees
and driver submissions.

We merge it under the light sensors because:

- It has similarities with the Capella CM3605 light sensor and
proximity driver which is there.

- It is related to the GP2AP020A00F driver which is also there.

This driver was tested with the Samsung GT-S7710 mobile phone
which has the GP2AP002S00F proximity sensor mounted.

The suspend/resume cycle will disable the interrupt from the
sensor. If someone would desire to use this interrupt for
wakeup, the driver will need modifications.
