Hi,

I'd like to use DS1374 watchdog capabilities. Is it correct to put the 
new stuff in the existing RTC driver (rtc/ds1374.c)? I was thinking 
about something like this:

#if (defined(CONFIG_RTC_DS1374)) &&

#if (CONFIG_COMMANDS & CFG_CMD_DATE)
	existing stuff
#endif

#if (CONFIG_WATCHDOG)
	new stuff
#endif

#endif

If it is not acceptable, where should I put the new stuff?


TIA,
llandre

I remember the u-boot of git support DS1374 RTC function.

I don't like this idea. Nobody will search  there  when  looking  for
watchdog code.

How much of such "new stuff" code will be needed? I guess  it's  just
some intialization, and eventually the trigger routine?

drivers/watchdog/ds1374.c ?

Best regards,

I see.

Yes, something like that.

Ok.
What about the common stuff (registers definitions for example) in order 
to avoid code duplication? Is it ok to add include/ds1374.h and to make 
and to make functions rtc_read and rtc_write_raw non-static?

What about this proposal?

Sounds ok to me.

Then the functions should probably be renamed, too.
