I customized the default Raspberry Pi 3 64-bit config, and I enabled
BR2_PACKAGE_NETWORK_MANAGER
and also BR2_PACKAGE_WPA_SUPPLICANT in order to connect to WPA networks.
I didn't enable BR2_PACKAGE_DHCPCD because I read it would prevent Network
Manager to work. Running the image, Network Manager find the interfaces
(eth0 and wlan0) but cannot use them:
# nmcli dev status
> DEVICE TYPE STATE CONNECTION
> lo loopback connected (externally) lo
> eth0 ethernet unavailable --
> wlan0 wifi unavailable --

I'm aware it's the expected behavior if the interface is present in
/etc/network/interfaces and I'm ok with eth0, but wlan0 should be available:
auto lo

The driver seems ok:
# lsmod | grep brcmfmac
> brcmfmac 270336 0
> brcmutil 24576 1 brcmfmac
> cfg80211 872448 1 brcmfmac

and iwconfig confirms the wlan0 is running:

I also tried ip link set wlan0 up but it does nothing, since the interface
is already up.
What else should I do in order to let Network Manager to use my wlan0?
I'm not sure what other info I may add to my question.
