Hi, I'm not sure what the strategy behind your cc:ing on this patch set is. I only got a couple of them in my inbox, and this one wasn't one of them. :) On Thu, Aug 20, 2015 at 10:46 AM, Jon Mason <jonmason@broadcom.com> wrote: > Add a very minimalistic set of Northstar Plus Device Tree files which > describes the SoC and the BCM958625 implementation.

Reviewed-by is one of those tags that has a value that's mostly dependent on who it comes from. By not actually seeing the review and the feedback provided (and revisions made), less data is provided to tell if it's a valuable review or not. Also, if you're posting the code you should probably have your name below Kapil's, since you're the one signing off the origin of the code.

It didn't seem to include you in all of them, but I thought the mailing list would be enough of a catch all. My apologies. I'll CC everyone listed as a maintainer on all of the patches in the future. > > On Thu, Aug 20, 2015 at 10:46 AM, Jon Mason <jonmason@broadcom.com> wrote: > > Add a very minimalistic set of Northstar Plus Device Tree files which > > describes the SoC and the BCM958625 implementation.

Best of all is to do more work in public, including sending the acks on the list. If you look around, it's relatively unusual that people post pre-acked or pre-reviewed patches, even corporate contributors. >> Also, if you're posting the code you should probably have your name >> below Kapil's, since you're the one signing off the origin of the >> code.

This was the first time I noticed BSD-only which is why I brought it up.

I've found there to be a slight drawback in upstreaming a system dtb before there's basic device support since it can't be used to determine whether a board is expected to have basic functionality or not. As long as it's in progress there's no big reason to hold off though. -Olof
