Nevertheless, to the extent that the set of pins is finite and well-defined, it should be possible to define a set of software interfaces to support the functionality represented by those pins. It might depend on the underlying SoC, but even so, it would still be best to encapsulate the interface set. I hear all these use cases that presuppose a wide variety of user skill sets. If one really wants to support such users well, it's important to define a coherent single point of interface. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
