The other thing is a single 4 cell address. It will get compiled to the same bytes, but the DT tools should complain about it, because it doesn't match #address-cells. > + reg-names = "main", "cec", "edid", "packet"; > > adi,input-depth = <8>; > adi,input-colorspace = "rgb"; > @@ -272,7 +279,8 @@ > > hdmi@39 { > compatible = "adi,adv7513"; > - reg = <0x39>; > + reg = <0x39 0x29 0x49, 0x59>; Same here. > + reg-names = "main", "cec", "edid", "packet"; > > adi,input-depth = <8>; > adi,input-colorspace = "rgb"; >
