Kernel-4.18.0-80.el8_omap-mcbsp

• Texas Instruments OMAP2+ McBSP module

Required properties:

• compatible: “ti,omap2420-mcbsp” for McBSP on OMAP2420

      "ti,omap2430-mcbsp" for McBSP on OMAP2430
      "ti,omap3-mcbsp" for McBSP on OMAP3
      "ti,omap4-mcbsp" for McBSP on OMAP4 and newer SoC
  

• reg: Register location and size, for OMAP4+ as an array:

   <MPU access base address, size>,
   <L3 interconnect address, size>;
  

• reg-names: Array of strings associated with the address space
• interrupts: Interrupt numbers for the McBSP port, as an array in case the

      McBSP IP have more interrupt lines:
  

  ,
  ,
  ;
• interrupt-names: Array of strings associated with the interrupt numbers
• interrupt-parent: The parent interrupt controller
• ti,buffer-size: Size of the FIFO on the port (OMAP2430 and newer SoC)
• ti,hwmods: Name of the hwmod associated to the McBSP port

Example:

mcbsp2: mcbsp@49022000 {
compatible = “ti,omap3-mcbsp”;
reg = <0x49022000 0xff>,
<0x49028000 0xff>;
reg-names = “mpu”, “sidetone”;
interrupts = <0 17 0x4>, /* OCP compliant interrupt /
<0 62 0x4>, / TX interrupt /
<0 63 0x4>, / RX interrupt /
<0 4 0x4>; / Sidetone */
interrupt-names = “common”, “tx”, “rx”, “sidetone”;
interrupt-parent = <&intc>;
ti,buffer-size = <1280>;
ti,hwmods = “mcbsp2”;
};
