This patch series implements a common PWM API. This series incorporates
the feedback from the linux-embedded mailing list and elsewhere; the author
greatly appreciates the efforts of everyone who reviewed the previous version
of this code.
Bill Gatliff (5):
API to consolidate PWM devices behind a common user and kernel
interface
Emulates PWM hardware using a high-resolution timer and a GPIO pin
Expunge old Atmel PWMC driver, replacing it with one that conforms to
the PWM API
PWM-based LED control
LED "dimmer" trigger
