TK1 mainline kernel + QCA6174A

Hi,
I want to use the QCA6174A chipset to add WLAN and BT functionality to a TK1. I installed the most recent mainline image to see if there is already build-in support. When i try to activate the card i get the error below. Maybe you can give me hint of how to reesolve this issues? Thanks in advance.

hciconfig hci0 up

Oops. Yes. The firmware was missing. Now it works. Thanks!

Have you tried putting that firmware on the module?
