- pinctrl-names: must contain a "default" entry.
- spi-num-chipselects : the number of the chipselect signals.
- bus-num : the slave chip chipselect signal number.
- big-endian : if DSPI modudle is big endian, the bool will be set in node.
Optional property:
- big-endian: If present the dspi device's registers are implemented
in big endian mode, otherwise in native mode(same with CPU), for more
detail please see: Documentation/devicetree/bindings/regmap/regmap.txt.
