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 v2 (Addressing feedback from Peter Meerwald + additional fixes) 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 Improve integration time parameter checks Clean up redundant return value assignments Fix broken lookup table algorithm Fix duplicate lookup table entry Disallow writing of negative event values The individual commits can be reviewed at: http://git.ti.com/cgit/cgit.cgi/ti-analog-linux-kernel/adannenb-analog.git/log/?h=opt3001 .../devicetree/bindings/iio/light/opt3001.txt | 18 + drivers/iio/light/Kconfig | 10 + drivers/iio/light/Makefile | 1 + drivers/iio/light/opt3001.c | 804 +++++++++++++++++++++ 4 files changed, 833 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/light/opt3001.txt create mode 100644 drivers/iio/light/opt3001.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
