My means apply two overlay files to dtb

imx93-9x9-qsb-tianma-tm050rdh03-dtbs += imx93-9x9-qsb.dtb imx93-9x9-qsb-ontat-kd50g21-40nt-a1.dtbo imx93-9x9-qsb-tianma-tm050rdh03.dtbo

In imx93-9x9-qsb-tianma-tm050rdh03.dtbo, only include
&{/} {
	panel {
		compatible = "tianma,tm050rdh03";
		enable-gpios = <&pcal6524 8 GPIO_ACTIVE_HIGH>;
	};
};
