Then, if we actually end up being able to convert to using dtc+cpp in 3.10, I'll create a new branch based on that for the conversion itself. Both you and I will need to rebase our conversion patches on top of all the other DT additions at that time. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I changed the patch subject to: ARM: tegra: add PWM nodes to Tegra114 DT tegra114: isn't a valid sub-system tag; it's tegra:.

Just like we do on Tegra20? Thierry

Just like we do on Tegra20? Oh yes. Thanks for catching that. I'll remove the patch from the Tegra tree for now until that's fixed. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Let me try that, using Tegra20 as guidance. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
