when to submit new board support

when to submit new board support

[Michael Jones]

I would like to submit some patches to add support for a new OMAP board...

Is there a right or wrong time to post such patches to this list? How
does the kernel merge window effect what kind of patches are expected
here on the OMAP list?

What should I use as the base for my patches? At
http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git,
at the moment 'master' hasn't been updated for 4 weeks. Should I base it
on v3.1-rc1 instead (as an example, since I won't manage to submit it
while v3.1-rc1 is the most recent tag)?

thanks,
Michael

Well this is the right time, however we're moving things to device tree
and coalescing code. So you may need to be prepared to update the patches
a few times before we get them to mainline.

Yes v3.1-rc1 should be used as the base. I've been on vacation and
have not updated the omap tree for a while, will updated it soonish,
but will be just v3.1-rc1 + bug fixes.

Hi Tony,

Thanks for the reply.

Unfortunately I am not ready to pull the trigger on submitting my code
right _now_, so I was hoping to get a better understanding of the
system- when the right time would be AND when the wrong time would be.
I.e. what makes "this" the right time?

Also, I'm uncertain whether my submission will generally be welcome. Are
there criteria for which boards are desirable to merge upstream? In
April [1] you said in response to the inquiry about submitting support
for the Nook Color that usually supporting a new machine adds "a few
tens of lines". My machine is not even on the market yet, and its board
file is currently 384 lines long, which is more than a few tens. I don't
want to submit unwanted bloat.

I'm not familiar yet with Device Tree, so I don't understand what the
implications are for existing supported boards and their board files,
but I would of course be prepared to make necessary changes after review.
