Hello community,   I am running Armbian taken from here on Radxa Rock 4c+. Everything I need seems to be in order (including wifi) but there appears to be no bluetooth device present (it is there using Radxa's images which have old kernels though). I tried to find out what could be the reason and noticed that dtb coming with Radxa has this:   wireless-bluetooth { uart0-gpios { rockchip,pins = <0x02 0x13 0x00 0xd0>; phandle = <0xf1>; }; };
