We are trying to create a custom I.MX6 board. I it we need to connect a audio source(PCM samples) via I2S to AUDMUX. We need to get this PCM data as such to a kernel buffer(With my understandig throug DMA). The kernel buffer need to know it only as a raw data. So we dont want the ALSA driver actualy. I there any way to bypass the ALSA driver?. Can we use any existing Freescale BSP for this purpose??
