I think I've found a solution while converting the R-Car Gen2 USB PHY bindings. You can mark channels 3-7 false on RZ/G2UL, cfr. the second channel on RZ/G1C in "[PATCH] dt-bindings: phy: renesas,rcar-gen2-usb-phy: Convert to json-schema" https://lore.kernel.org/r/8e48edc5e7b65f8dfd8b76c583e0265b9b97e62b.1652099944.git.geert+renesas@xxxxxxxxx/ Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@xxxxxxxxxxxxxx In personal conversations with technical people, I call myself a hacker.
