+NVIDIA Tegra114 pinmux controller
+
+The Tegra114 pinctrl binding is very similar to the Tegra20 and Tegra30
+pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
+nvidia,tegra30-pinmux.txt. In fact, this document assumes that binding as
+a baseline, and only documents the differences between the two bindings.
+
+Required properties:
+- compatible: "nvidia,tegra114-pinmux"
+- reg: Should contain the register physical address and length for each of
+  the pad control and mux registers. The first bank of address must be the
+  driver strength pad control register address and second bank address must
+  be pinmux register address.
+
+Tegra114 adds the following optional properties for pin configuration subnodes:
+- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
+- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
+- nvidia,lock: Integer. Lock the pin configuration against further changes
+    until reset. 0: no, 1: yes.
+- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
+- nvidia,rcv-sel: Integer. Select VIL/VIH receivers. 0: normal, 1: high.
+- nvidia,drive-type: Integer. Valid range 0...3.
+
+As with Tegra20 and Terga30, see the Tegra TRM for complete details regarding
+which groups support which functionality.
+
+Valid values for pin and group names are:
+
+  per-pin mux groups:
+
+    These all support nvidia,function, nvidia,tristate, nvidia,pull,
+    nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
+    nvidia,io-reset and nvidia,rcv-sel.
