Dear Maintainer,
Please update QCA6930 firmware to the latest version. At the time of
writing (https://github.com/kvalo/ath11k-firmware, commit 0497fb0):
* amss.bin, m3.bin - from https://github.com/kvalo/ath11k-firmware/tree/master/QCA6390/hw2.0/1.0.1/WLAN.HST.1.0.1-05266-QCAHSTSWPLZ_V2_TO_X86-1/
* board-2.bin - from https://github.com/kvalo/ath11k-firmware/blob/master/QCA6390/hw2.0/board-2.bin

This firmware seems to provide substantial stability and power
management benefits (C10 state is now achievable) on my Dell XPS 13 9310
Laptop with QCA6390 wifi. Even s2idle/resume became stable with 5.19
kernel (currently at rc4, from Debian experimental).
