struct pwm_args — board-dependent PWM arguments
struct pwm_args {
unsigned int period;
enum pwm_polarity polarity;
}; This structure describes board-dependent arguments attached to a PWM device. These arguments are usually retrieved from the PWM lookup table or device tree.
Do not confuse this with the PWM state: PWM arguments represent the initial configuration that users want to use on this PWM device rather than the current PWM hardware state.
