Did you do a grep on the code to see? $ git grep ti,omap3 arch/arm/mach-omap2/ arch/arm/mach-omap2/board-generic.c: "ti,omap3430", arch/arm/mach-omap2/board-generic.c: "ti,omap3", arch/arm/mach-omap2/board-generic.c: "ti,omap36xx", arch/arm/mach-omap2/board-generic.c: "ti,omap3-beagle", This is the same as keystone's device support. even though only 36xx was needed, we introduced other SoC specific compatibility match. > "ti,k2hk-evm", "ti,k2hk", "ti,keystone" > > So unless there is an exception, there is no need for a SoC specific > string in the compatibility string list.

My view was based on "be accurate in the hardware description" OK - i will probably agree on the topic. But, how about userspace needing to know which SoC they are on, without needing to depend on board->soc mapping? How do we help resolve that? -- Regards, Nishanth Menon -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
