-/**
- * @file
- * @brief Clocksource based on the 'Programmable Interval Timer' PIT (8253)
- *
- * This timer should be available on almost all PCs. It also should be run
- * at a fixed frequency (1193181.8181 Hz) and not modified to use another
- * reload value than 0xFFFF. So, it always counts from 0xffff down to 0.
- *
- * @note: We can't reprogram the PIT, it will be still used by the BIOS. This
- * clocksource driver does not touch any PIT settings.
