Enable the onboard QCA Wi-Fi. HW identifiers for reference:
qmi chip_id 0x320 chip_family 0x4001 board_id 0xff soc_id 0x400e0000
Firmware sources:
/vendor/firmware_mnt/image/wlanmdsp.bin -> qcom/.../wlanmdsp.mbn
/vendor/firmware_mnt/image/bdwlan.bXX [1] -> [2] -> ath10k/.../board-2.bin
[3] -> ath10k/.../firmware-5.bin
Not sure where 3 comes from on the device itself, gotta investigate that..
According to [4], it's called WCN3990_STRAIT.
Enable it and tighten the relevant regulators.
[1] XX = board_id printed when the file is missing or by your downstream
kernel firmware loader in the dmesg; if XX=ff, use bdwlan.bin
