Individual ioread32() time has been observed to jump from 15-20 ticks to > 80k ticks followed by a secure-watchdog bite and a system reset. Work around this corner case by only issuing the read transaction when the driver state is ATH10K_STATE_ON.

I can add that to the commit log.
HW = QCA9988 FW = ?? Not quite sure how to find the firmware version TBH
