See ../pinctrl/pinctrl-bindings.txt for details of the property values.
- big-endian: Boolean property, required if all the SAI device registers
are big-endian rather than little-endian.
-- big-endian-data: If this property is absent, the little endian mode will
- be in use as default, or the big endian mode will be in use for all the

+- msb-first: Configures whether the LSB or the MSB is transmitted first for
+ the fifo data. If this property is absent, the LSB is transmitted first as
+ default, or the MSB is transmitted first.
- fsl,sai-synchronous-rx: This is a boolean property. If present, indicating
that SAI will work in the synchronous mode (sync Tx with Rx) which means
both the transimitter and receiver will send and receive data by following
