+Nuvoton NPCM7xx Pulse-width modulation (PWM) controller device driver
+
+The NPCM7xx has two identical PWM controller modules,
+Each module has four PWM controller outputs.
+NPCM7xx PWM controller module 0 outputs PWM0-3 and NPCM7xx PWM controller
+module 1 outputs PWM4-7.
+
+Required properties:
+- compatible : "nuvoton,npcm750-pwm" for Poleg NPCM7XX.
+- reg : Offset and length of the registers set for the device.
+- clocks : phandle of pwm reference clock.
+- pinctrl-names : a pinctrl state named "default" must be defined.
+- pinctrl-0 : phandle referencing pin configuration of the PWM ports.
+
+pwm:pwm@f0103000 {
+ compatible = "nuvoton,npcm750-pwm";
+ reg = <0xf0103000 0x50
+ 0xf0104000 0x50>;
+ clocks = <&clk NPCM7XX_CLK_APB3>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pwm0_pins &pwm1_pins
+ &pwm2_pins &pwm3_pins
+ &pwm4_pins &pwm5_pins
+ &pwm6_pins &pwm7_pins>;
+};
