I have an IPQ40xx board which is based on dk04.1-c1.
I try to build an OpenWrt firmware, but can't get wireless working.
I've tried:
Using board-2.bin from ath10k-firmware directly;
Building a custom board-2.bin with ath10k-bdencoder and adding qcom,ath10k-calibration-variant = "model"; to dts wifi node;
Neither worked

I Googled it and found that it might be a driver bug
https://patchwork.ozlabs.org/patch/839338/
https://lists.infradead.org/pipermail/ath10k/2016-November/008761.html
But these were posted years ago and should be fixed already.
Any idea what's happening?
