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 - 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

24 compatible = "ti,omap3-mcbsp";

27 reg-names = "mpu", "sidetone";
28 interrupts = <0 17 0x4>, /* OCP compliant interrupt */
29 <0 62 0x4>, /* TX interrupt */
30 <0 63 0x4>, /* RX interrupt */
31 <0 4 0x4>; /* Sidetone */
32 interrupt-names = "common", "tx", "rx", "sidetone";
33 interrupt-parent = <&intc>;
34 ti,buffer-size = <1280>;
35 ti,hwmods = "mcbsp2";
