| * This is the frequency of the timer used for Linux's timer interrupt. |
| * The value should be defined as accurate as possible or under certain |
| * circumstances Linux timekeeping might become inaccurate or fail. |
| * For many system the exact clockrate of the timer isn't known but due to |
| * the way this value is used we can get away with a wrong value as long |
| * - a divisor of the actual rate |
| * 500000 is a good such cheat value. |
| * The obscure number 1193182 is the same as used by the original i8254 |
| * time in legacy PC hardware; the chip is never found in AVR32 systems. |
