enum pwm_polarity

enum pwm_polarity - polarity of a PWM signal : a high signal for the duration of the duty- cycle, followed by a low signal for the remainder of the pulse period : a low signal for the duration of the duty- cycle, followed by a high signal for the remainder of the pulse period

Enumerator:

PWM_POLARITY_NORMAL
PWM_POLARITY_INVERSED

Function Documentation

int pwm_set_polarity	(	struct pwm_device *	pwm,
		enum pwm_polarity	polarity
	)

pwm_set_polarity() - configure the polarity of a PWM signal : PWM device : new polarity of the PWM signal

Note that the polarity cannot be configured while the PWM device is enabled
