Doing this in the buses is definitely wrong, as you say it's not bus specific. I do however think we can usefully do this stuff in a SoC specific place like a power domain, keeping the SoC integration code together and out of the drivers. IME the SoCs where you need to do different things for different IPs shoudl mostly still get some reuse out of such an approach. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
