Three comments
1. Use inlines not defines when you can - it means we get type
checking
2. There is an RTC timer interface - could you use that interface
for some of this so its compatible and consistent ?
3. Ditto for a watchdog use - although that would be a separate
driver using the kernel hooks anyway.
