What about using ranges here? The binding would look way cleaner, like:

         jpeg-encoder@1a030000 {
                .... properties ....
                ranges = <0x30000   0 0x1a030000 0x10000>, /* P.S.: Not tested! */
                         <0x1030000 0 0x1b030000 0x10000>;

                encoder-core@30000 {
                         compatible = "mediatek,mt8195-jpgenc-hw";
                         reg = <0 0x30000 0 0x10000>;
                         .... properties ....
                };

                encoder-core@1030000 {
                         compatible = "mediatek,mt8195-jpgenc-hw";
                         reg = <0 0x1030000 0 0x10000>;
                         .... properties ....
                };
         };

P.S.: Added Krzysztof to the loop.

Krzysztof, can you please give an opinion on that?

Thanks,
Angelo
