[PATCH v3 0/2] iio: light: add support for TI's opt3001 light sensor

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



TI's opt3001 light sensor is a simple and yet powerful
little device. The device provides 99% IR rejection,
automatic full-scale, very low power consumption and
measurements from 0.01 to 83k lux.

This patch adds support for that device using the IIO
framework.

See http://www.ti.com/product/opt3001 for more information.

Patch History:
v3
  Add "ti,opt3001" device tree compatible string
  Add device tree binding documentation

  Fix restoring of IRQ mutex functionality in error case
  Use managed IIO device alloc/registration
  Add parenthesis to improve formula readability
  Fix error message number formatting
