Commit 23fb05c688a8dcb0cf6a4d8d819cffeca82e5c54 upstream. Applies on 3.10.x.
Due to a bug with RTC IMR, we cannot consider at91sam9x5 RTC compatible
with the previous one. Modify DT compatibility string, even if the driver
is not yet modified to take it into account.

Hi,
Some comments concerning this patch:
- removed the use of macro for interrupts property
- as Douglas Gilbert described:
"without this patch members of the at91sam9x5 family (e.g. at91sam9g25) that
use the RTC will receive an unhandled interrupt whenever they try to write
to the RTC. In the case of 9x5 SoCs that is the SYS interrupt shared with
several other things such as the debug port. Thereafter the debug port
becomes useless (for input), the RTC doesn't work ..."
