Here is the example why I need this, see the dts node here: lvds@ff2e0000 { ... rockchip,grf = <&grf>; port { port@0 { endpoint@0 { remote-endpoint = <&vopl_out_lvds>; } } } } We can only get 'grf' udevice by uclass_get_device_by_phandle(), but we not able to get udevice 'vopl_out_lvds', other driver like rockchip pinctrl also need to get udevice by a phandle which is not one of direct property of another device node.
