DAI_CLOCK(fsync, 48000, codec_slave),Does this hardwire SSP (I2S) sample rate to 48 kHz? It's not critical now but I'd imagine that there might be need for other sample rates in some special applications (save power or have some IC in the system without 48k support).
No this is just a test m4 file. We can change the sample rate as needed.
