The two should be able to coexist happily, regmap-mmio requires the caller to do the actual mapping and so long as you don't cache the relevant registers the two shouldn't interfere with each other. Alternatively, and more generally usefully, we could implement regmap based common clock helpers. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
