I am sorry, but i don't see dependency between the dts > definition and this patch. Could you explain please? IMHO the dependancy is that DEBUG_LL uses the uart device, and this is added when you add the dts. AFAIK there can arise problems with multi-platform kernels if the uart is not present. > > Thanks, > Georgi > -- motzblog.wordpress.com -- To unsubscribe from this list: send the line "unsubscribe linux-arm-msm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
