+NXP TPM PWM controller
+
+Required properties:
+- compatible: should be "nxp,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.
+- nxp,pwm-number: the number of PWM devices
+
+Example:
+
+pwm0: tpm@40250000 {
+       compatible = "nxp,tpm-pwm";
+       reg = <0x40250000 0x1000>;
+       nxp,pwm-number = <6>;
+       #pwm-cells = <2>;
+};
