It seems that only up-to-date router hardware and/or software are 
supported, not any older router hardware and/or software. Only router 
where are I have successfully created WPA2-PSK connection on linux with 
QCA9377 is my Android 5.1.1 (CM12.1) cellphone, but when I testing same 
with older Android 4.2.2 device, 4-way handshake is always 
unsuccessfully with current ath10k driver despite correct pre-shared 
key. Also I can't create WPA-PSK connection to Android 4.2.2 wifi 
hotpoint. Other wlan chips works correctly, so I think that is ath10k 
related issue, maybe WPA-PSK/WPA2-PSK support for older router device 
is not fully implemented to ath10k driver.
