+Description:
+ A read/write property to provide capability to delay reporting of
+ samples till a timeout is reached. This allows host processors to
+ sleep, while the sensor is storing samples in its internal fifo.
+ The maximum timeout in seconds can be specified by setting
+ hwfifo_timeout.The current delay can be read by reading
+ hwfifo_timeout. A value of 0 means that there is no timeout.
