In linux kernel since version 5.1 (release Date: 2019-05-05)
This driver supports the Freescale SAI (Synchronous Audio Interface)
to be used as a generic clock output. Some SoCs have restrictions
regarding the possible pin multiplexer settings. Eg. on some SoCs
two SAI interfaces can only be enabled together. If just one is
needed, the BCLK pin of the second one can be used as general
purpose clock output. Ideally, it can be used to drive an audio
codec (sometimes known as MCLK).
