So if mt7621 routers are using pcie1 and 2, that's a bug in the DTS files.
- Changing pcie0 to pcie1/mt761,0 and pcie1 to pcie2/mt762,0 has no effect. But maybe the mt76-nodes should not be updated? I will test on my device.
- When looking at dmesg, the pci device-paths are the same for the two wifi radios on the WE1326 and WG3526 (one is at 0000:01:00.0 and the other at 0000:02:00.0).
Changing pcie0 to pcie1/mt761,0 and pcie1 to pcie2/mt762,0 has no effect. But maybe the mt76-nodes should not be updated? I will test on my device.
I test this again, both with and without updating the mt76 noedes. Changing pcie has no effect, but maybe I am missing something.
I can’t test it now, but just a thought on PCIe0. Very likely this is wired to the PCIe slot (at least in the ZBT) for an extra 3g/4g/LTE card. I don’t have a unit with this option. The card is ordered but is still “shipping”.
I have two variants of the same board, one in which the wifi is surface mounted, and the other where they are mPCIe slots. They both show up in almost the same way. On the smt board they are 0000:01:00.00 and 0000:02:00.0, on the board with the slots they are 2 and 3. Both boards have a pcie slot used for LTE
After reverted NeilBrown's patches I can see both phy0 and phy1 but no wifi can be brought up:

There is a hostapd-phyX.conf, but no wifi-phyX.pid file
The proper values should be shown by lspci from pciutils. On my board, pcie stuff is 0,1,2 and devices are 1,2,3.
On ZBT1326 5G is on bus1 with INT24, 2.4Ghz is on bus2 with INT25, both are up, however 2.4G can not connect. I noticed via 'wifi status' that 5Ghz is phy1-radio0-wlan1 while 2.4Ghz is phy0-radio1-wlan0, the naming seems confusing to me. will work on this later.

It's hard to keep track of who is using the staging PCI driver and who is not.
Anyway, can we start to make a list of routers along with the mt76 IRQs? The relevant numbers are in column 8 of /proc/interrupts . They are 4, 24, and 25 with 7 added to each, so 11, 31, 32.
edit: I am also interested in people that can get wifi working with the staging driver by changing the DTS files like this.
I do not see 4 here, just 24 and 25, zbt we1326 that is

If it goes from 16 to 18, it's staging. 16 to 19 is stock IIRC. master has it reverted.
The ramips-mt76 revert patches are now in openwrt-18.06 branch, just built and tested on zbt1326 and both 2.4G/5G are working.
Snapshot r7093-4fdc6ca31b installed on Netgear R6220 and both 2.4GHz and 5GHz WiFi are working.
What do you mean?
after about 20+ reboots it no longer reboots reliably, not even into recovery mode, I then solder the uart and found either the kernel boots half-way and die, or nothing coming out of the uart at all, it's dead/unusable after 2 days. -- update, after a fresh rebuild it boots up fine, it could be my build-env is not distclean-ed after so many rebuilds.
