It has been verified in digital loopback mode. The patch includes the following features. 1. McBSP enabled in defconfig 2. Supporting all the LP features. 3. Support of DMA chaining mode and one time configuration for entire transfer to improve performance. 4. Independent configurations and transfer of Rx and Tx 5. MCBSP data transfer in 8, 16 and 32 bit mode. 6. instead of mcbsp client configuring all the register, it allows clients to configure parameters like clk polarity, clk src and other parameters.
