| * iio: chemical: Add IIO_CONCENTRATION channel typeMatt Ranostay2015-09-231-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | There are air quality sensors that report data back in parts per million of VOC (Volatile Organic Compounds) which are usually indexed from CO2 or another common pollutant. This patchset adds an IIO_CONCENTRATION type that returns a percentage of substance because no other channels types fit this use case. Modifiers for IIO_MOD_CO2 and IIO_MOD_VOC gas types are defined.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver currently registers a pair of irq handlers using request_threaded_irq(), however the synchronization mechanism between the hardirq and the threadedirq handler is a regular spinlock. Unfortunately, this breaks PREEMPT_RT builds, where a spinlock can sleep, and is thus not able to be acquired from a hardirq handler. This patch gets rid of the threaded handler and pushes all interrupt handling into the hardirq context, and uses request_irq().
