You should perhaps check if (ratio >= 1 && ratio <= 256) prior to
accepting a divider that can't be programmed? But maybe that's enforced
somewhere else? And perhaps the sanity check should be even stricter?
Yes it should be stricter with a power of two only. I tried really hard
to make this codec work with ratios of 50 (and a 19.2 MHz mclk) on an Up
board and it's just not possible, probably not supported by hardware.
