+Freescale i.MX TPM PWM controller
+
+Required properties:
+- compatible : Should be "fsl,imx-tpm-pwm".
+- reg: Physical base address and length of the controller's registers.
+- #pwm-cells: Should be 2. See pwm.txt in this directory for a description of the cells format.
+- clocks : The clock provided by the SoC to drive the PWM.
+- interrupts: The interrupt for the pwm controller.
+
+Example:
+
+pwm0: tpm@40250000 {
+	compatible = "fsl,imx-tpm-pwm";
+	reg = <0x40250000 0x1000>;
+	assigned-clocks = <&clks IMX7ULP_CLK_LPTPM4>;
+	assigned-clock-parents = <&clks IMX7ULP_CLK_SOSC_BUS_CLK>;
+	clocks = <&clks IMX7ULP_CLK_LPTPM4>;
+	#pwm-cells = <2>;
+};
