- 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>;
- interrupts-names = "rx", "tx";
- dmas = <&edma0 3 1
- &edma0 2 1>;
- dma-names = "tx", "rx";
- status = "okay";
- };
