On what firmware version? I run it on a Qualcomm RB3 board with Qualcomm SDM845 and WCN3990. However on that kernel I did not manage to WiFi actually work - regardless of that patch - so I would no count it yet as fully tested. It would be great if someone would provide some tests. I saw Steev's replies - thanks! Best regards, Krzysztof

Interrupt line can be configured on different hardware in different way, even inverted. Therefore driver should not enforce specific trigger type - edge rising - but instead rely on Devicetree to configure it. All Qualcomm DTSI with WCN3990 define the interrupt type as level high, so the mismatch between DTSI and driver causes rebind issues: $ echo 18800000.wifi > /sys/bus/platform/drivers/ath10k_snoc/unbind $ echo 18800000.wifi > /sys/bus/platform/drivers/ath10k_snoc/bind [ 44.763114] irq: type mismatch, failed to map hwirq-446 for interrupt-controller@17a00000!
