[PATCH v3 2/4] iio: chemical: add driver for dsm501/ppd42ns particle sensors

2017-02-09 Thread Tomasz Duszynski
This patch adds support for dsm501 and ppd42ns particle sensors. Both sensors work on the same principle. Heater (resistor) heats up air in sensor chamber which induces upward flow. Particles convect up through a light beam provided by internal infra-red LED. Light scattered by particles is picked
