It's sounding like if we should be doing it this is a general thing which we should be constraining presumably it'd apply to all drivers, not just this one, and so shouldn't be being fixed in the driver but it's not obvious to me why the period constraint isn't sufficient.
It can only be done if we have fixed FIFO for the dai. Right now this is kind of true for McASP. In HW we actually have 64 32bit word FIFO and currently you can set the desired FIFO depth via DT/pdata. I'm not really happy about this
Sorry, what I meant was more the bit where you were setting the constraint on both the buffer and the period than the constraint itself - that seemed somehow redundant.
