The Avago APDS9930 has the same register set as the TAOS/AMS TSL2772 so this patch adds the correct device tree bindings and the appropriate LUX table values based on 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> --- .../devicetree/bindings/iio/light/tsl2772.txt | 1 + drivers/iio/light/tsl2772.c | 18 ++++++++++++++++-- 2 files changed, 17 insertions(+), 2 deletions(-)
