+
+Required properties:
+- compatible : "fsl,mcf-dspi"
+- #address-cells: <1>, as required by generic SPI binding
+- #size-cells: <0>, also as required by generic SPI binding
+- reg : offset and length of the register set for the device
+
+Optional properties:
+- spi-max-frequency : max supported spi frequency
+- num-cs : the number of the chipselect signals
+- spi-mode: spi motorola mode, 0 to 3
+- ctar-params: CTAR0 to 7 register configuration, as an array
