That's not way to describe syscon phandle. Property name is ok. For the rest look at: https://elixir.bootlin.com/linux/v5.18-rc1/source/Documentation/devicetree/bindings/soc/samsung/exynos-usi.yaml#L42 Anyway, this looks like SoC-specific hack, so it does not really fit to the driver. You have to think of something generic. Best regards, Krzysztof
