    pwm: Introduce the pwm_args concept · e39c0df1
    Boris Brezillon authored
    Currently the PWM core mixes the current PWM state with the per-platform
    reference config (specified through the PWM lookup table, DT definition
    or directly hardcoded in PWM drivers).
    Create a struct pwm_args to store this reference configuration, so that
    PWM users can differentiate between the current and reference
    Patch all places where pwm->args should be initialized. We keep the
    pwm_set_polarity/period() calls until all PWM users are patched to use
    pwm_args instead of pwm_get_period/polarity().
