The PWM module uses a standard character - driver framework. However, since the PWM driver is a devices + driver framework. However, since the PWM driver is a device control interface and not a data transfer interface, the majority of the functionality available to the application is implemented in driver ioctl calls. - **"Upper Half" Driver**.
