+OMAP2+ McSPI device
+
+Required properties:
+- compatible :
+ - "ti,omap2-spi" for OMAP2 & OMAP3.
+ - "ti,omap4-spi" for OMAP4+.
+- ti,spi-num-cs : Number of chipselect supported by the instance.
+- ti,hwmods: Name of the hwmod associated to the McSPI
+
+
+Example:
+
+mcspi1: mcspi@1 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "ti,omap4-mcspi";
+ ti,hwmods = "mcspi1";
+ ti,spi-num-cs = <4>;
