This confused me for a second, as there was no driver to replace when I wrote
the pwm-pca9685 driver and I thought I missed something. But it seems I didn't
and the pwm-pca9685 is actually older.

If the platform setup is needed, maybe this can be integrated into the pwm driver
instead of completely dropping it. I don't care for platform code, but if someone
does, I don't want him to lose the support for it.

Otherwise I am okay with this drop (okay, I'm completely biased of course ;-)).
But technically the pca9685 is not solely a LED driver IC, but a PWM IC, so it
is in the wrong place anyhow.

Steffen
