Hi,
Thanks for the patch, this looks good.
One thing about the error messages though.

order the code to look like
case 5400:
if (source != ADAV80X_PLL_SRC_XIN)
return -EINVAL;
pll_ctrl1 |= ADAV80X_PLL_CTRL1_PLLDIV;
break;
It is just as many lines added when adding the /* fall through */, but it
makes it more obvious what is going on.
Either way:

Documentation?
We already have the altvoltage channel type with the frequency attribute.
Difficult to say if there are any overlaps without documentation

This is a threaded interrupt. Sleeping is OK.

Same question was also posted on the ADI support forums, we'll discuss it
there since this is a ADI product specific question.
