- Say Y here to enable RTC timer support for ALSA. ALSA uses
- the RTC timer as a precise timing source and maps the RTC
- timer to ALSA's timer interface. The ALSA sequencer code also
- can use this timing source.
-
- To compile this driver as a module, choose M here: the module

- Say Y here to use the RTC timer as the default sequencer
- timer. This is strongly recommended because it ensures
