PWM_REQUEST_FROM_CHI(9)            Pulse-Width Modulation (PWM)           PWM_REQUEST_FROM_CHI(9)



NAME
       pwm_request_from_chip - request a PWM device relative to a PWM chip

SYNOPSIS
       struct pwm_device * pwm_request_from_chip(struct pwm_chip * chip, unsigned int index,
                                                 const char * label);

ARGUMENTS
       chip
           PWM chip

       index
           per-chip index of the PWM to request

       label
           a literal description string of this PWM

RETURN
       A pointer to the PWM device at the given index of the given PWM chip. A negative error
       code is returned if the index is not valid for the specified PWM chip or if the PWM device
       cannot be requested.
