[PATCH v3 2/2] devicetree: Add documentation for UPISEMI us5182d ALS and Proximity sensor
From: Adriana Reus <hidden>
Date: 2015-08-14 09:29:55
Also in:
linux-iio, lkml
Subsystem:
i2c subsystem host drivers, iio subsystem and drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Andi Shyti, Jonathan Cameron, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
Added entries in trivial-devices and i2c/vendor-prefixes for the us5182d als and proximity sensor. Also added a documentation file for this sensor's properties.
