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.
