94cd1113aa iio: tsl2772: add support for reading proximity led settings from device tree 
This patch adds support for optionally reading the proximity led diode
and current settings from device tree. This was tested using a LG
Nexus 5 (hammerhead) which requires a different diode than the driver
default for the IR LED.

288320f6e9 iio: tsl2x7x/tsl2772: avoid potential division by zero 
It may be possible for tsl2772_get_lux to return a zero lux value
and hence a division by zero can occur when lux_val is zero. Check
for this case and return -ERANGE to avoid the division by zero.
