Kernel-4.18.0-80.el8_davinci-mcbsp

Texas Instruments DaVinci McBSP module

This binding describes the "Multi-channel Buffered Serial Port" (McBSP)
audio interface found in some TI DaVinci processors like the OMAP-L138 or AM180x.


Required properties:

• compatible :

    "ti,da850-mcbsp" : for DA850, AM180x and OPAM-L138 platforms
  

• reg : physical base address and length of the controller memory mapped

    region(s).
  

• reg-names : Should contain:

    * "mpu" for the main registers (required).
    * "dat" for the data FIFO (optional).
  

• dmas: three element list of DMA controller phandles, DMA request line and
  TC channel ordered triplets.

• dma-names: identifier string for each DMA request line in the dmas property.
  These strings correspond 1:1 with the ordered pairs in dmas. The dma
  identifiers must be “rx” and “tx”.

Optional properties:

- interrupts : Interrupt numbers for McBSP
- interrupt-names : Known interrupt names are "rx" and "tx"

- pinctrl-0: Should specify pin control group used for this controller.
- pinctrl-names: Should contain only one value - "default", for more details
        please refer to pinctrl-bindings.txt

Example (AM1808):

mcbsp0: mcbsp@1d10000 {
compatible = “ti,da850-mcbsp”;
pinctrl-names = “default”;
pinctrl-0 = <&mcbsp0_pins>;

reg =     <0x00110000 0x1000>,
    <0x00310000 0x1000>;
reg-names = "mpu", "dat";
interrupts = <97 98>;
interrupt-names = "rx", "tx";
dmas = <&edma0 3 1
    &edma0 2 1>;
dma-names = "tx", "rx";

};
