They aren't really proprietary, they are proper patches that were submitted as RFC once, so it shouldn't be much effort to port them to e.g. 4.7.

Your options are either to disable support for them in the kernel config, or pass irq_mode=1 to ath10k_pci on probe to force legacy interrupts; it should work then properly. Regards Jonas
