++ * @mck: base clock rate, which can be prescaled and maybe subdivided
+ *
-+ * Copyright (C) 2005-2006 Atmel Corporation
++ * Drivers initialize a pwm_channel structure using pwm_channel_alloc().
++ * Then they configure its clock rate (derived from MCK), alignment,
++ * polarity, and duty cycle by writing directly to the channel registers,
++ * before enabling the channel by calling pwm_channel_enable().
+ *
-+ * This program is free software; you can redistribute it and/or modify
-+ * it under the terms of the GNU General Public License version 2 as
-+ * published by the Free Software Foundation.
++ * After emitting a PWM signal for the desired length of time, drivers
++ * may then pwm_channel_disable() or pwm_channel_free(). Both of these
++ * disable the channel, but when it's freed the IRQ is deconfigured and
++ * the channel must later be re-allocated and reconfigured.
++ *
++ * Note that if the period or duty cycle need to be changed while the
++ * PWM channel is operating, drivers must use the PWM_CUPD double buffer
++ * mechanism, either polling until they change or getting implicitly
++ * notified through a once-per-period interrupt handler.
