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"; };
