1 Texas Instruments DaVinci McBSP module
2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
4 This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
5 audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.
11 "ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
13 - reg : physical base address and length of the controller memory mapped
15 - reg-names : Should contain:
16 * "mpu" for the main registers (required).
17 * "dat" for the data FIFO (optional).
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".
27 - interrupts : Interrupt numbers for McBSP
28 - interrupt-names : Known interrupt names are "rx" and "tx"
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
