+Freescale Enhanced Serial Audio Interface (ESAI) Controller
+
+The Enhanced Serial Audio Interface (ESAI) provides a full-duplex serial port

+ "fsys" The system clock derived from ahb clock used to derive

+ contains audio controls, audio interface capabilities, codec DAPM
+ definition and codec IO functions. This class extends to BT, FM and MODEM
+ ICs if required. Codec class drivers should be generic code that can run
+ on any architecture and machine.
- * Platform driver: The platform driver contains the audio DMA engine and audio
- interface drivers (e.g. I2S, AC97, PCM) for that platform.
+ * Platform class drivers: The platform class driver includes the audio DMA
+ engine driver, digital audio interface (DAI) drivers (e.g. I2S, AC97, PCM)
+ and any audio DSP drivers for that platform.
- * Machine driver: The machine driver handles any machine specific controls and
- audio events (e.g. turning on an amp at start of playback).
+ * Machine class driver: The machine driver class acts as the glue that
+ decribes and binds the other component drivers together to form an ALSA
+ "sound card device". It handles any machine specific controls and
+ machine level audio events (e.g. turning on an amp at start of playback).
