BTW, re: the new pinmux API: I have a driver for both Tegra20 and Tegra30 now which should work for muxing. All the data is present for all the pin configs too (tri-state, pull, ...) but we need to define the core pinctrl API for this before I can expose that. Similarly, we need DT bindings for all of this before we can make use of it; something I hope to start work on in the near future. -- nvpublic -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
