As to facilitate work items preemption, common for sensor read ops. e.g: - Sensor read (submitted through workqueue). - SPI read (submitted through workqueue using default handler). This requires at least 2 thread pools to allow SPI read to complete, to then come back and complete sensor reading. Signed-off-by: Luis Ubieda <luisf@croxel.com>
