The difference here is that the LED, backlight, etc are all different
physical devices begin driven by the pwm pin, so it makes sense to have a
device tree node for them, while using the pwm as gpio is just a different
function of the same physical pin.  So in a sense the pwm controller also
becomes a gpio controller. I like the idea of the pwm core automatically
instantiating a pwm-gpo device if it sees a gpio-controller property in the
pwm device devicetree node.

OK, fair enough. I will go with the plan I described in the first mail for the
GPIO use of PWM.
