Hi, Here is a patch that adds dma chaining support for McBSP on 34XX. It has been verified in digital loopback mode. It Supports DMA chaining mode and one time configuration for entire transfer to improve performance. instead of mcbsp client configuring all the register, it allows clients to configure parameters like clk polarity, clk src sample rate. It also supports data transfer in 8,16,32 bit mode. ( 16 and 24 bit stereo and mono ).
