   1 * Texas Instruments OMAP2+ McBSP module
   2
   3 Required properties:
   4 - compatible: "ti,omap2420-mcbsp" for McBSP on OMAP2420
   5               "ti,omap2430-mcbsp" for McBSP on OMAP2430
   6               "ti,omap3-mcbsp" for McBSP on OMAP3
   7               "ti,omap4-mcbsp" for McBSP on OMAP4 and newer SoC
   8 - reg: Register location and size, for OMAP4+ as an array:
   9        <MPU access base address, size>,
  10        <L3 interconnect address, size>;
  11 - reg-names: Array of strings associated with the address space
  12 - interrupts: Interrupt numbers for the McBSP port, as an array in case the
  13               McBSP IP have more interrupt lines:
  14         <OCP compliant irq>,
  15         <TX irq>,
  16         <RX irq>;
  17 - interrupt-names: Array of strings associated with the interrupt numbers
  18 - interrupt-parent: The parent interrupt controller
  19 - ti,buffer-size: Size of the FIFO on the port (OMAP2430 and newer SoC)
  20 - ti,hwmods: Name of the hwmod associated to the McBSP port
  21
  22 Example:

  30                      <0 62 0x4>, /* TX interrupt */
  31                      <0 63 0x4>, /* RX interrupt */

  34         interrupt-parent = <&intc>;
  35         ti,buffer-size = <1280>;
  36         ti,hwmods = "mcbsp2";
