status last

pinctrl-n goes before pinctrl-names

No underscores in node names, pinctrl children node names
must end in -state. Please check your patches against

mux {} / config {} is unnecessary. You can simply do:

{
    pins = "gpio56";
    function = "pcie_clkreq";
    drive-strength = <2>;
    bias-disable;
};
