This series implements a generic PWM device API.
Bill Gatliff (7):
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
Implements PWM-based LED control
LED "dim" trigger based on PWM control of the LED
Incorporate PWM API code into KBuild
PWM API driver for MPC52xx GPT peripheral
