It is bad overlay.
It works with the following overlay:
/dts-v1/;
/plugin/;
/ {
compatible = "allwinner,sun8i-h3";
fragment@0 {
target-path = "/aliases";
__overlay__ {
serial1 = "/soc/serial@01c28400";
};
};
fragment@1 {
target = <&uart1>;
__overlay__ {
pinctrl-names = "default";
pinctrl-0 = <&uart1_pins>;
status = "okay";
};
};
};
