Interrupt line can be configured on different hardware in different way,So you tested on WCN3990? On what firmware version? I can add the
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!
[ 44.763130] ath10k_snoc 18800000.wifi: error -ENXIO: IRQ index 0 not found
[ 44.763140] ath10k_snoc 18800000.wifi: failed to initialize resource: -6
Tested-on tag if you provide that.
