+* 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
+- interrupt-parent: The parent interrupt controller
+- 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";
