+* Texas Instruments OMAP2+ McBSP module
+
+Required properties:
+- compatible: "ti,omap2420-mcbsp" for McBSP on OMAP2420
+	      "ti,omap2430-mcbsp" for McBSP on OMAP2430
+	      "ti,omap3-mcbsp" for McBSP on OMAP3
+	      "ti,omap4-mcbsp" for McBSP on OMAP4 and newer SoC
+- reg: Register location and size, for OMAP4+ as an array:
+       <MPU access base address, size>,
+       <L3 interconnect address, size>;
+- reg-names: Array of strings associated with the address space
+- interrupts: Interrupt numbers for the McBSP port, as an array in case the
+	      McBSP IP have more interrupt lines:
+	<OCP compliant irq>,
+	<TX irq>,
+	<RX irq>;
+- interrupt-names: Array of strings associated with the interrupt numbers
+- ti,buffer-size: Size of the FIFO on the port (OMAP2430 and newer SoC)
+- ti,hwmods: Name of the hwmod associated to the McBSP port
+
+Example:
+
+mcbsp2: mcbsp@49022000 {
+	compatible = "ti,omap3-mcbsp";
+	reg = <0x49022000 0xff>,
+	      <0x49028000 0xff>;
+	reg-names = "mpu", "sidetone";
+	interrupts = <0 17 0x4>, /* OCP compliant interrupt */
+		     <0 62 0x4>, /* TX interrupt */
+		     <0 63 0x4>, /* RX interrupt */
+		     <0 4 0x4>;  /* Sidetone */
+	interrupt-names = "common", "tx", "rx", "sidetone";
+	interrupt-parent = <&intc>;
+	ti,buffer-size = <1280>;
+	ti,hwmods = "mcbsp2";
+};
