The other type is some mfd drivers which implement the pwm API themselves
right now. These are currently incompatible with the pwm framework anyway.
If a board wants to connect the mfd pwm to its backlight, the current
pwm_request based on an integer id is not suitable anymore. We need
a (struct device *dev, char *id) based pwm_request function then.
So my plan is to change the pwm API once we have all in tree drivers
in drivers/pwm.

Ok, sounds good. I don't much like the idea of using a string identifier
for this, but let's discuss that when we get there. Using fixed numbers
for the first version seems totally reasonable, as it keeps the existing
API.
