[linux-yocto] [PATCH 00/18] Re-submit upgrades to the lsi 3.10 axxia

Ultimately we need to get these patches up to the LTSI.  It would make things easier, right now we are on a strict time schedule and we need to get the standard/axxia/base branch corrected with proper checkpatching  and the latest changes.

We have a few more patches to submit and then we can concentrate on getting in onto LTSI.

Can we just get passed  this push.

:-) Yes, I'm aware of what a backport is.

It's a great deal more effort to continually forward port this work as the linux-yocto kernel tracks mainline than it is to get it into mainline first and then pull it back once to linux-yocto, and the following versions come for free since you got it upstream. You get the added benefit of higher quality code having gone through the rigorous code review process of getting it into the mainline kernel.

I would suggest you consider LTSI as a backport point if you need a longer term stable point for productization as well as this provide even more eyes on your code, additional validation and QA from other users of LTSI, etc. LTSI gets pulled into linux-yocto as a matter of course.
