+Freescale i.MX TPM PWM controller
+
+Required properties:
+- compatible : Should be "fsl,imx-tpm".
+- reg: Physical base address and length of the controller's registers.
+- #pwm-cells: Should be 3. 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.
+
+Note: The TPM counter and period counter are shared between multiple channels, so all channels
+should use same period setting.
+
+Example:
+
+pwm0: tpm@40250000 {
+ compatible = "fsl,imx-tpm";
+ 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 = <3>;
+};
