This suggests that you have a bug in your suspend and resume implementation, possibly outside of this driver.
The driver works absolutely fine in case of suspend to ram where the power domains (which includes the I2S controller) is switched off.
That doesn't mean everything is OK, for example the clock tree or DMA controller might not be preserving state properly.
As the soc-core.c misses hibernation call backs of dev_pm_ops, we were wondering whether it has been tested before on some other platform.
Not to my knowledge, but I don't see any reason why anything more than the trivial implementation should really be needed except for the general pointlessness of resuming after hibernating.
