LPC32XX PWM controller Required properties: - compatible: should be "nxp,lpc3220-pwm" - reg: physical base address and length of the controller's registers Examples: pwm@4005c000 { compatible = "nxp,lpc3220-pwm"; reg = <0x4005c000 0x4>; }; pwm@4005c004 { compatible = "nxp,lpc3220-pwm"; reg = <0x4005c004 0x4>; };
