Matt Ranostay b11a34607d iio: health: max30100: add config for LED current 
Allow the current for both RED and IR LEDs to be set via an device tree
property setting.

This is an optional setting that is useful for applications that have a
known glass attenuation factor.

Matt Ranostay 4d33615df5 iio: light: add MAX30100 oximeter driver support 
MAX30100 is an heart rate and pulse oximeter sensor that works using
two LEDS of different wavelengths, and detecting the light reflected
back.

This patchset adds support for both IR and RED LED channels which can
be processed in userspace to determine heart rate and blood oxygen
levels.
