2018-08-19iio: tsl2772: add support for regulator frameworkBrian Masney
This patch adds support for the regulator framework to the tsl2772 driver. Driver was tested using a LG Nexus 5 (hammerhead) phone with the two regulators and on a Raspberry Pi 2 without any regulators controlling the power to the sensor.

2018-08-18iio: tsl2772: add support for avago,apds9930Brian Masney
The Avago APDS9930 has the same register set as the TAOS/AMS TSL2772 so this patch adds the correct bindings and the appropriate LUX table values derived from the values in the datasheet. Driver was tested on a LG Nexus 5 (hammerhead) phone. avago,apds9930 datasheet: https://www.mouser.com/datasheet/2/678/avago_AV02-3190EN_DS_APDS-9930_2014-03-25[1]-1217273.pdf tsl2772 datasheet: https://ams.com/eng/content/download/291503/1066377/file/TSL2772_DS000181_2-00.pdf Signed-off-by: Brian Masney <masneyb@onstation.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2018-08-18iio: tsl2772: add support for reading proximity led settings from device treeBrian Masney
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.

2018-06-24iio: tsl2x7x/tsl2772: avoid potential division by zeroColin Ian King
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.
