The ti-aemif platform driver also does clk_get(). Don't you need lookups to make that work as well? For example, DA830 doesn't have a clock lookup for aemif at all. -- To unsubscribe from this list: send the line "unsubscribe linux-clk" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

For example, DA830 doesn't have > a clock lookup for aemif at all. > This seems like a bug: in arch/arm/mach-davinci/aemif.c in current mainline we do call clk_get() for 'aemif' and it's called indirectly from board-da830-evm.c via davinci_aemif_setup(). I'll address this too in v2.
