This patch series introduces a new function u32 ktime_get_resolution_ns(void) and shows how this would be used in a driver that greatly benefits from it. Since the iio subsystem has it's own wrapper function iio_get_time_ns() for timestamps a similiar wrapper iio_get_time_resolution_ns() is introduce in Patch 2 to keep the API consistent. Patch 3 updates the example driver. Patch 3 depends on other fixes currently only iio.git. If Patch 3 can't be picked up now then it will be resent with more cleanup patches to dht11.c later - the main goal for now is, to get the new code for timekeeping reviewed and merged.
