Maybe this can also get Could you expand on how you see that being implemented, please? It doesn't feel entirely comfortable to me - providing a bus for the chip seems more direct and the platform bus not what I'd think of using for something hanging off another bus - but I think I'm just not visualising what you're thinking of properly. > help from soon-to-be posted MFD (multi function devices) helpers. The multi-function device support does feel like it could be a good fit. I'd seen it discussed sometime last year but don't recall seeing anything for quite a while. Like Ben said, any pointers to current work would be appreciated. It's probably worth mentioning that in addition to what is in the current patch series these chips all also provide an audio codec which requires a reasonably substantial driver for full support. -- 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/
