Subject: [PATCH 0/2] iio: light: Add support for Capella cm36686 and
 cm36672p sensors

This patch series adds support for Capella cm36686 and cm36672p ambient
light and proximity sensors.

Capella cm36686 is a combined ambient light and proximity sensor with
adjustable integration time, interrupt and hysteresis support. It has
the slave address of 0x60. cm36672p is fully compatible with cm36686,
except that it is a proximity-only sensor.

Unfortunately, datasheets for these sensors are not publicly
available. This code is based on Android downstream kernels for devices
which did use these sensors and a previous submission for cm36672p to
mailing lists:
https://github.com/LineageOS/android_kernel_xiaomi_msm8992/blob/cm-14.1/drivers/iio/light/cm36686.c
https://github.com/shakalaca/ASUS_ZenFone_ZD551KL/blob/android-6.0/kernel/drivers/input/misc/cm36283.c
https://lore.kernel.org/linux-iio/1465462845-1571-1-git-send-email-capellamicro@gmail.com/

The following code has been tested on Asus ZenFone 2 Laser/Selfie, which
uses cm36686 as its ambient light and proximity sensor.
