The -rc5 cutoff isn't a hard line.  It's also mvebu-specific.  eg, We
need things _posted_ a week or so before arm-soc's cutoff of -rc6 so we
have time to get the pull request in.  If it needs to go through
mvebu/arm-soc, once it's posted, you're good.

The rtc driver shouldn't go through mvebu/arm-soc.  It should go through
the rtc maintainer's tree.

Unfortunately, it doesn't look like Alessandro has been active for a
while and Andrew Morton has indeed been picking up the slack.  S-o-B's
confirm this.

I haven't worked with Andrew enough to know his workflow, but I imagine
he can take patches much closer to the merge window than we can.

I don't mind routing it though mvebu/arm-soc since the only consumers
are currently mvebu boards, but I'd like to hear from Andrew that this
is ok.

In the long term, should we seek out a co-maintainer for drivers/rtc?
Can anyone get a hold of Alessandro to get his opinion on this?

thx,

Jason.
