/sys/class/rtc/rtcX/date and /sys/class/rtc/rtcX/time currently have
read-only access. This patch introduces write functionality which will
set the rtc time.

Usage: echo YYYY-MM-DD > /sys/class/rtc/rtcX/date
echo HH:MM:SS > /sys/class/rtc/rtcX/time
Why do we want to add a new interface here?

I'm not adding a new interface. The current date/time interface only handles
read and I'm introducing write.

Right, but what benefit does that provide?
(I'm not saying there isn't any, its just not clear from your patch why this is a good thing.)

Also CC'ing Alessandro for his input.
