13 description: The Tegra124 pinctrl binding is very similar to the Tegra20 and
14 Tegra30 pinctrl binding, as described in nvidia,tegra20-pinmux.yaml and
15 nvidia,tegra30-pinmux.yaml. In fact, this document assumes that binding as a
16 baseline, and only documents the differences between the two bindings.
