I can never quite keep it straight how this is supposed to work, but since previously only "rockchip,rk3288-usb-phy" was supported and now we have these new compatible strings, I would have expected the new strings to specify the old ones as fallback. That would mean your choices would be: - "rockchip,rk3288-usb-phy" - A real rk3288 - "rockchip,rk3188-usb-phy", "rockchip,rk3288-usb-phy" - A rk3188 with fallback to 3288 driver. - "rockchip,rk3066a-usb-phy", "rockchip,rk3288-usb-phy" - A rk3066a with fallback to 3288 driver. That means that if you land the dts changes without the driver changes that things still work OK. -Doug -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
