+Bindings for a PWM based Tachometer driver
+
+Required properties:
+- compatible: Must be "nvidia,tegra186-pwm-tachometer"
+- reg: physical base addresses of the controller and length of
+  memory mapped region.
+- #pwm-cells: should be 2. See pwm.txt in this directory for a
+  description of the cells format.
+- clocks: phandle list of tachometer clocks
+- clock-names: should be "tachometer". See clock-bindings.txt in documentations
+- resets: phandle to the reset controller for the Tachometer IP
+- reset-names: should be "tachometer". See reset.txt in documentations
+- nvidia,pulse-per-rev: Integer, pulses per revolution of a Fan. This value
+  obtained from Fan specification document.
+- nvidia,capture-window-len: Integer, window of the Fan Tach monitor, it 
indicates
+  that how many period of the input fan tach signal will the FAN TACH logic
+  monitor. Valid values are 1, 2, 4 and 8 only.
+
+Example:
+   tegra_tachometer: tachometer@39c {
+   compatible = "nvidia,tegra186-pwm-tachometer";
+   reg = <0x0 0x039c 0x0 0x10>;

+   clock-names = "tachometer";
+   resets = <_car TEGRA186_RESET_TACH>;
+   reset-names = "tachometer";
+   nvidia,pulse-per-rev = <2>;
+   nvidia,capture-window-len = <2>;
+   status = "disabled";
