One last question though. What about power management ?
For example, in pwm_bl, pwm_backlight_suspend calls:
pwm_config(pb->pwm, 0, pb->period);
pwm_disable(pb->pwm);
Which is fine because it will correctly set up the PWM to a low level.
Then, to disable the pwm itself and its clock, I suppose we would have
to define some pm_ops in atmel_pwm, am I right ?
So we will have to be extra careful to correctly set a low level on the
pin at that time.
Thanks,
