Liam, I have a rough peek into the git tree on opensource.wolfsonmicro.com, find another PMIC framework, and here instead is a regulator framework, looks like a simplified or dedicated one. What is their relationship? For those PMIC that covers additional features, like - usb vbus detection (or pull-up/pull-down) - audio codec - touch screen - battery monitor/ fuel gauge - battery charger - possible many others How do you plan to handle them? > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to [EMAIL PROTECTED] > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ > -- Cheers - eric -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
