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:
23	
24	mcbsp2: mcbsp@49022000 {
25		compatible = "ti,omap3-mcbsp";
26		reg = <0x49022000 0xff>,
27		      <0x49028000 0xff>;
28		reg-names = "mpu", "sidetone";
29		interrupts = <0 17 0x4>, /* OCP compliant interrupt */
30			     <0 62 0x4>, /* TX interrupt */
31			     <0 63 0x4>, /* RX interrupt */
32			     <0 4 0x4>;  /* Sidetone */
33		interrupt-names = "common", "tx", "rx", "sidetone";
34		interrupt-parent = <&intc>;
35		ti,buffer-size = <1280>;
36		ti,hwmods = "mcbsp2";
37	};
