+Allwinner sun8i R40/V40/T3 SoC PWM controller
+
+Required properties:
+ - compatible: Should be one of:
+ - "allwinner,sun8i-r40-pwm"
+ - reg: Physical base address and length of the controller's registers
+ - interrupts: Should contain interrupt.
+ - clocks: From common clock binding, handle to the parent clock.
+ - clock-names: Must contain the clock names described just above.
+ - pwm-channels: PWM channels of the controller.
+ - #pwm-cells: Should be 3. See pwm.txt in this directory for a description of
+ the cells format.
+
+Example:
+
+pwm: pwm@1c23400 {
+ compatible = "allwinner,sun8i-r40-pwm";
+ reg = <0x01c23400 0x400>;
+ interrupts = <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&osc24M>, <&ccu CLK_APB1>;
+ clock-names = "mux-0", "mux-1";
+ pwm-channels = <8>;
+ #pwm-cells = <3>;
+};
