We're trying to switch to the of_graph way of representing connected
panels. With that, the above phandle will go away. This needs to be
replaced with:
port {
lvds_out: endpoint {
remote_endpoint = <&auo_in>;
};
};
+ lvds-vccs-3p3v-supply = <&ext_3p3v>;
+ lvds-pll-vdda-supply = <&pm8921_l2>;
+ lvds-vdda-supply = <&pm8921_lvs7>;

+ backlight: backlight{

+ pinctrl-names = "default";
+ compatible = "gpio-backlight";

+
+ ddc-i2c-bus = <&i2c3>;
+ backlight = <&backlight>;
+ power-supply = <&panel_3p3v>;
and for the panel:
port {
auo_in: endpoint {
remote-endpoint = <&lvds_out>;
};
};
