With that, I don't know how to explain it in more detail; this thing is literally just a few magic registers that route into some CPU control logic to trigger frequency/voltage transitions :) Mikko > > Acked-by: Rob Herring <robh@kernel.org> > >> >> Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> >> --- >> .../arm/tegra/nvidia,tegra186-ccplex-cluster.txt | 17 +++++++++++++++++ >> 1 file changed, 17 insertions(+) >> create mode 100644 Documentation/devicetree/bindings/arm/tegra/nvidia,tegra186-ccplex-cluster.txt > -- > 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 > -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

That's all I'm asking for.
