-Subject: [PATCH] ath10k: Delay device access after cold reset
-
-It is observed that during cold reset pcie access right
-after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
-Data Bus Error and system hard lockup. The reason
-for bus error is that pcie needs some time to get
-back to stable state for any transaction during cold reset. Add
-delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
-to fix this issue.
