[RFC 0/4] iio: light: add driver for Broadcom APDS9999

["Jose A. Perez de Azpillaga" <azpijr@gmail.com>]

This series adds support for the Broadcom APDS9999 ambient light
sensor. The APDS9999 is a digital proximity and RGB sensor with
ALS capability, featuring I2C interface, programmable gain and
integration time.

This chip is considered by Broadcom to be the 'successor' to the
APDS-9960 which has technically been discontinued.

The initial driver implements the ALS/Lux functionality using the
green channel, which approximates the human eye spectral response.

Sent as RFC to gather feedback on the driver structure
and DT binding.
