I came across the support for EMD1 in mater branch and tried it on the device I have access to. Things are looking good (it needs separate board file from package ipq-wifi-engenius_emd1). I have observed couple of issues with 5GHz, the main one being if I configure it to be both 'station' and 'ap', although there are no errors in log and hostapd says that AP has started successfully the SSID can't be found from other devices. If put 5Ghz only in AP mode it works fine. There is no similar issue with 2GHz. I have tried all firmware and driver combinations (ct, ct-htt, non-ct) the issue remains the same.
The other issue being 5Ghz as station connecting my Netgear WAC124 puts out

Looking for some help on this to get 5GHz going in AP and Station mode.
