[yocto] How to submit patches upstream for repos at git.yoctoproject.org (eg meta-renesas)

[Paul Sherwood]

Hi all,
I am not affiliated to any Yocto Project member organisation, but am 
assisting with integration at the Automotive Grade Linux project, which 
is re-using some work from upstreams at git.yoctoproject.org

Recently members of the AGL community have started contributing patches 
for meta-renesas at our mirror [1]. We would like to offer this and 
future work to upstream, and I am hoping to understand so that I can 
help guide AGL's activities so that we are properly aligned. Please can 
someone guide us on the accepted way to offer these and subsequent 
patches?

br
Paul
