In particular initrd is quite custom to hardcode like that. > --- /dev/null > +++ b/arch/arm/boot/dts/exynos5250.dtsi > @@ -0,0 +1,413 @@ > +/* > + * SAMSUNG EXYNOS5250 SoC device tree source > + * > + * Copyright (c) 2012 Samsung Electronics Co., Ltd. > + * http://www.samsung.com > + * > + * SAMSUNG EXYNOS5250 SoC device nodes are listed in this file. > + * EXYNOS5250 based board files can include this file and provide > + * values for board specfic bindings. > + * > + * Note: This file does not include device nodes for all the controllers in > + * EXYNOS5250 SoC.

Also, technically no need to specify a unit address (@<foo>) in the device node name unless you need it to tell more than one entry apart, but it's become customary to always add them on ARM for some reason. -Olof -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
