adding QCA6174 chipset support to 3.10 kernel

[bartlomiej.grzeskowiak]

Hi, 

Our embedded device works with 3.10 kernel. Since it is not within our 
responsibility it is not easy to upgrade the whole kernel. We would like to 
use the WLAN card with QCA6174 chipset. 

I have found out, that QCA6174 chipset is first supported in 3.20 kernel. 
ath10k driver that services this chipset is first introduced in 3.11.

What would you recommend to achieve it ?

Thank you for answers
