When upgrading to 5.3 my AP started to work really slow. I tracked the problem to 4504f0e5b5714d9d26b1a80bf1fc133c95830588 and fixed the issue.

For the record, that's:
4504f0e5b571 ath10k: sdio: workaround firmware UART pin configuration bug



The attached patch fixes the issue when uart_print is false and uart_pin_workaround also false.

-ENOPATCH

Sorry, I sent it in a different email "attached to the thread", but in any case, there was the same fix already applied to kvalo's tree.

Here is the patch and link to already applied fix:

It would be great if we can get this to stable, in my case, my WiFi speed went from 150 Mbit/s to 1-5 Mbit/s without this fix.
