Well, I wasn't asking for decisions. I asked what are the technical
differences between the options. If this driver would be implemented as
a PWM driver, and you'd use pwm-leds, how would that affect your use case?

If I'm not mistaken, the only argument so far you've given was that the
device cannot implement the pwm_config() call correctly, but Peter
argued that it doesn't matter, other PWM devices cannot do that either.

I want the driver to work for all the users, and as I'm not that
familiar with leds and pwms I need to ask these questions.
