Will add: The micfil hardware provides the microphone data on multiple successive FIFO registers, one register per stereo pair. Also to work properly the SDMA_DONE0_CONFIG_DONE_SEL bit in the SDMA engines SDMA_DONE0_CONFIG register must be set. This patch provides the necessary information to the SDMA engine driver.
