I think you need to specify the literal values here as well, since the binding must be fully self-contained. That is you can't rely on the DT binding to be bundled with the exynos-simple-phy.h header. > @@ -20,3 +20,4 @@ phy-exynos-usb2-$(CONFIG_PHY_EXYNOS4X12_USB2) += phy-exynos4x12-usb2.o > phy-exynos-usb2-$(CONFIG_PHY_EXYNOS5250_USB2) += phy-exynos5250-usb2.o > obj-$(CONFIG_PHY_EXYNOS5_USBDRD) += phy-exynos5-usbdrd.o > obj-$(CONFIG_PHY_XGENE) += phy-xgene.o > +obj-$(CONFIG_EXYNOS_SIMPLE_PHY) += exynos-simple-phy.o Perhaps this should be named phy-exynos-simple for consistency?

But in general the driver core will already complain if the driver fails to probe, so there's in general no need to mention when it probes successfully. > diff --git a/include/dt-bindings/phy/exynos-simple-phy.h b/include/dt-bindings/phy/exynos-simple-phy.h [...] > +/* simeple phys */ s/simeple phys/simple PHYs/ Although on second thought that comment probably shouldn't be there in the first place. > +#define INVALID (~1) This doesn't belong in this header.

It's not a value that will ever appear in a DT source file. Thierry
