     * 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";
    };
