* iio: Fix parameters in iio_triggered_buffer_setupCristina Opriceana2015-07-052-8/+8
| | | | | | | | | | | This patch renames the top half handler and the bottom half handler of iio_triggered_buffer_setup() in accordance with their usage. The bottom half has been renamed to reflect the fact that it is a thread based call, compliant with iio_alloc_pollfunc(). The names of the parameters were swapped, thus creating confusion.

* iio: allow userspace to flush the hwfifo with non-blocking readsOctavian Purdila2015-06-211-9/+9
| | | | | | | | | | | | | | This patch changes the semantics of non-blocking reads so that a hardware fifo flush is triggered if the available data in the device buffer is less then the requested size. This allows userspace to accurately generate hardware fifo flushes, by doing a non-blocking read with a size greater then the sum of the device buffer and hardware fifo size.

| | | | | | | | | | | | | | | | | The ADC is typically shared with remote CPUs not running Linux. However, there is only one register to power-up/power-down. Remote CPUs aren't able to power-up the ADC, and rely in Linux doing it instead. This commit uses the adc-reserved-channels devicetree property to distinguish shared usage. In this case, the ADC is powered up at probe time. If the ADC is used only by the CPU running Linux, power-up/down at runtime, only when neeeded.
