Microchip AT91 PWM controller for SAMA5D2
Required properties:
- compatible: Should be "atmel,sama5d2-pwm"
- reg: Physical base address and length of the controller's registers.
- clocks: Should contain a clock identifier for the PWM's parent clock.
- #pwm-cells: Should be 3.
Example:
pwm0: pwm@f802c000 {
compatible = "atmel,sama5d2-pwm";
reg = <0xf802c000 0x4000>;
clocks = <&pwm_clk>;
#pwm-cells = <3>;
};
