1Texas Instruments DaVinci McBSP module
2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
3
4This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
5audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.

7
8Required properties:
9~~~~~~~~~~~~~~~~~~~~
10- compatible :
11        "ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
12
13- reg : physical base address and length of the controller memory mapped
14        region(s).
15- reg-names : Should contain:
16        * "mpu" for the main registers (required).
17        * "dat" for the data FIFO (optional).
18
19- dmas: three element list of DMA controller phandles, DMA request line and
20	TC channel ordered triplets.
21- dma-names: identifier string for each DMA request line in the dmas property.
22	These strings correspond 1:1 with the ordered pairs in dmas. The dma
23	identifiers must be "rx" and "tx".
24
25Optional properties:
26~~~~~~~~~~~~~~~~~~~~
27- interrupts : Interrupt numbers for McBSP
28- interrupt-names : Known interrupt names are "rx" and "tx"
29
30- pinctrl-0: Should specify pin control group used for this controller.
31- pinctrl-names: Should contain only one value - "default", for more details
32        please refer to pinctrl-bindings.txt

34Example (AM1808):
35~~~~~~~~~~~~~~~~~
36
37mcbsp0: mcbsp@1d10000 {
38	compatible = "ti,da850-mcbsp";
39	pinctrl-names = "default";
40	pinctrl-0 = <&mcbsp0_pins>;
41
42	reg = 	<0x00110000 0x1000>,
43		<0x00310000 0x1000>;
44	reg-names = "mpu", "dat";
45	interrupts = <97 98>;
46	interrupt-names = "rx", "tx";
47	dmas = <&edma0 3 1
48		&edma0 2 1>;
49	dma-names = "tx", "rx";
50	status = "okay";
51};
