Hi

I'm working on having pcm1792a and omap platform. Right now I have already sent and rfc for the codec and I have a local build that change this file too to support 192000. What I don't understand is the meaning of:

.period_bytes_min = 32,

What is the relation between fifo_size and period_bytes_min? because at this frequency 32 bytes are not so much and the fifo of the port are >= 512 bytes. Is it possible to increase the period_bytes_min without violating the hw constraints?

Michael

.period_bytes_max = 64 * 1024, .periods_min = 2, .periods_max = 255, .buffer_bytes_max = 128 * 1024,
