Can you try using --find-copies-harder when making this patch or I think Denys likes -m.  That will help to minimize the actual patch difference in cases like this where you are based on an existing recipe.

I think you might want to set a DEFAULT_PREFERRENCE = -1 here.  Since you are going to use your branding config to select this kernel vs. the linux-ti-staging kernel this should be no issue.  That way there isn't a confusion about with basic meta-ti what kernel is being picked up.

Sorry to nit-pick here, but any reason to re-use the tag name from the linux-ti-staging tree?  The reason I ask is back to it being confusing if I have two trees with the same tag name (including version) it becomes kind of confusing.  Especially since this tree is part of the same git.ti.com project as the other one.  Thoughts?

Go ahead and reset your append here to a+ gitr${SRCPV}.  No need to start from f.

Thanks for the submission.  Overall looks pretty good, just a few things to fix up.
