I assume you're planning on adding more IDs later, in a backwards-compatible fashion? I suppose that's OK since it won't break any existing usage, as long as there's no need to renumber any existing values. On that topic, are any of those clock IDs derived from HW, e.g. register numbers, or bit numbers in an array of registers? Numbering clocks in a HW-derived fashion would make it easier or more obvious how to add new clock IDs later while maintaining some consistency and without introducing the desire to break any ABI. Finally, how about creating a header file such as include/dt-bindings/clock/exynos5410.h to define those clock IDs, so that both *.dts and the clock driver can share the values without having to manually write them? -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
