The device is going to need a clock that's in spec to make sure that the
device performs in spec, if the device is clocked from a 32kHz clock
(which is quite a common configuration and one that's supported by the
machine driver since it gets the clock from DT) that's definitely not
going to be the case and I'd not expect it to work at all sensibly.
