FS#3093 - RAMIPS/MT7621: 2,4 GHz radio not recognised in master.

[openwrt-bot]

Borromini:

OpenWrt master r13212-300b7fe85a does not recognise the 2,4 GHz radio on the DIR-860L B1.

After a 'wifi config' only the 5 GHz radio is shown:

# cat /etc/config/wireless

config wifi-device 'radio0'
option type 'mac80211'
option channel '36'
option hwmode '11a'
option path '1e140000.pcie/pci0000:00r13212-300b7fe85a/0000:00:00.0/0000:01:00.0'
option htmode 'VHT80'
option disabled '1'

config wifi-iface 'default_radio0'
option device 'radio0'
option network 'lan'
option mode 'ap'
option ssid 'OpenWrt'
option encryption 'none'

Great, so I forgot to add the router to the title and I cannot change that anymore.

Dmesg for completeness, it's not showing anything weird AFAICT:

[ 1.146383] mt7621-pci 1e140000.pcie: Parsing DT failed

Borromini:

Thanks Adrian. I found [[https://lists.infradead.org/pipermail/openwrt-devel/2020-April/022762.html|his message from April on the mailing list]], indicating the wifi chip does not fully initialise with the new PCI driver (which is probably part of the 5.4 bump?).

I went to the end of that e-mail thread but no solution from what I can tell.

Edit: I found a few of Sergio's patches sitting in the [[https://git.openwrt.org/?p=openwrt/openwrt.git;a=tree;f=target/linux/ramips/patches-5.4|target/linux/ramips/patches-5.4 subdir]] for the mt7621 PCIe driver, but I have no idea where to go from here.

Commit [[https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=d21d6ea4547412632e01de505b7a2c8a83817a02|d21d6ea4547412632e01de505b7a2c8a83817a02]] introduced that driver.

Borromini:

Well, I don't know what happened... But after a bit of back and forth between 19.07 and master images (to test other things) the 2,4 GHz radio is back. So I'm closing this for now.
