15  * INDIO_BUFFER_FLAG_FIXED_WATERMARK - Watermark level of the buffer can not be
16  *   configured. It has a fixed value which will be buffer specific.

29  * @set_length:		set number of datums in buffer
30  * @enable:             called if the buffer is attached to a device and the

37  * @modes:		Supported operating modes by this buffer type
40  * The purpose of this structure is to make the buffer element
42  * different buffer designs (space efficiency vs speed for example).
