FM350-GL and BE14 finally works on BPI-R4

Banana Pi Router design BPI-R4/BPI-R4 Pro(MT7988)

Where is the source for this overlay? Do you only set status of pci2 to disabled?

44

Yes, src - me =)

 /dts-v1/;
/plugin/;

/ {
    compatible = "bananapi,bpi-r4", "mediatek,mt7988";

    fragment@0 {
        target = <&pcie2>;
        __overlay__ {
            status = "disabled";
        };
    };
};

You could convert it like this (imho much more readable) and upstream it with description why this is useful

Thanks for the advice, but I have absolutely no experience with this. Could I ask you to do this, if it’s not too much trouble, thank you!

Should look like something like this

// SPDX-License-Identifier: (GPL-2.0 OR MIT)
/*

/dts-v1/;
/plugin/;

/ {
	compatible = "bananapi,bpi-r4", "mediatek,mt7988a";
};

&{/soc/pcie@11280000} {
	status = "disabled";
};

Put in the directory where mt7988a.dtsi is and add line in Makefile to let it compile like in my patch above

edit: added overlay to my repo
