Banging my head in the wall for some hours seems to have resulted in a solution.
The default PCIe interrupt mapping in mt7621.dtsi is wrong for WE1326.
After taking a look at which IRQs were set up before commit
5f7396ebef09, I noticed that the IRQs in mt7621.dtsi. After adding the
following to the pcie-node of ZBT-WE1326.dts, wifi is working fine:
interrupt-map = <0x10000 0 0 1 &gic GIC_SHARED 24 IRQ_TYPE_LEVEL_HIGH>,
<0x20000 0 0 1 &gic GIC_SHARED 25 IRQ_TYPE_LEVEL_HIGH>;
I will prepare and submit a patch.
