  1. * Texas Instruments OMAP2+ McBSP module
  2. Required properties:
  3. - compatible: "ti,omap2420-mcbsp" for McBSP on OMAP2420
  4. "ti,omap2430-mcbsp" for McBSP on OMAP2430
  5. "ti,omap3-mcbsp" for McBSP on OMAP3
  6. "ti,omap4-mcbsp" for McBSP on OMAP4 and newer SoC
  7. - reg: Register location and size, for OMAP4+ as an array:
  8. <MPU access base address, size>,
  9. <L3 interconnect address, size>;
  10. - reg-names: Array of strings associated with the address space
  11. - interrupts: Interrupt numbers for the McBSP port, as an array in case the
  12. McBSP IP have more interrupt lines:
  13. <OCP compliant irq>,
  14. <TX irq>,
  15. <RX irq>;
  16. - interrupt-names: Array of strings associated with the interrupt numbers
  17. - interrupt-parent: The parent interrupt controller
  18. - ti,buffer-size: Size of the FIFO on the port (OMAP2430 and newer SoC)
  19. - ti,hwmods: Name of the hwmod associated to the McBSP port
  20. Example:
  21. mcbsp2: mcbsp@49022000 {
  22. compatible = "ti,omap3-mcbsp";
  23. reg = <0x49022000 0xff>,
  24. <0x49028000 0xff>;
  25. reg-names = "mpu", "sidetone";
  26. interrupts = <0 17 0x4>, /* OCP compliant interrupt */
  27. <0 62 0x4>, /* TX interrupt */
  28. <0 63 0x4>, /* RX interrupt */
  29. <0 4 0x4>; /* Sidetone */
  30. interrupt-names = "common", "tx", "rx", "sidetone";
  31. interrupt-parent = <&intc>;
  32. ti,buffer-size = <1280>;
  33. ti,hwmods = "mcbsp2";
  34. };
