If that clashed in any way with other numbered names, I suggest to rename to "gpio-port" as actually the controller is the parent node and this represents one port (in the nomenclature of DW-APB-GPIO). > + compatible =3D "snps,dw-apb-gpio-port"; > + gpio-controller; > + #gpio-cells =3D <2>; > + snps,nr-gpios =3D <32>; 32 gpio pins for each of the 6 GPIO controllers? Either BG2Q is a GPIO beast or it is a mistake :P Can you please double-check? I am fine with using nr-gpios property now, but I guess BG2Q also has that CONFIG[1,2] registers to actually read out the features synthesized in? If I find some time, I'll prepare a patch for dw-apb-gpio to exploit that (optional) information instead of using nr-gpios.
