The conversion itself is good but one thing:

...

for (i = 0; i < ARRAY_SIZE(ssm2602_reg); i++)
snd_soc_write(codec, i, cache[i]);

The core cache sync stuff would be good here - that can be fixed in an incremental patch if Liam is OK with this version.

is there an existing codec driver you can highlight that does what you're saying here ?

and i would prefer to have an incremental patch done after this one, but obviously i'll send out a new one that doesnt depend on the previous commit (sample rate changes). -mike

I suspect this change is incomplete and should also be setting the symmetric_rates flag in the driver which does the equivalent thing in the core as this code is doing. Looking at the code some symmetry handling is required as the driver is setting the same registers for playback and capture rates so simultaneous playback and record with different rates is not supported?

Converting to symmetric_rates would definitely be a good thing.

i imagine you're right on all these points. this change was necessary as it's easy to see errors in sample rate conversion or even hangs. hopefully Cliff can find some time for this as the words you use go right over my head ;). -mike
