-config CS5535_CLOCK_EVENT_SRC
- tristate "CS5535/CS5536 high-res timer (MFGPT) events"
- depends on GENERIC_TIME && GENERIC_CLOCKEVENTS && CS5535_MFGPT
- help
- This driver provides a clock event source based on the MFGPT
- timer(s) in the CS5535 and CS5536 companion chips.
- MFGPTs have a better resolution and max interval than the
- generic PIT, and are suitable for use as high-res timers.
