I would add a few things that we had to go through before for Broadcom SoCs:

- send your pull requests to arm@...nel.org and copy Arnd, Olof and Kevin

- you would want to get your PGP key signed by as many people as people as possible which should not be a problem if you are in an area with lots of kernel people like the Bay Area (which reminds me I should do that)

- if you are going to be reasonably active every cycle consider getting a kernel.org account to host your tree (we are still not doing that...)

- for future pull requests, you might want to break them into e.g: DTS, board/Kconfig, drivers, defconfig, maintainers file, and have as little dependencies between each branch to minimize merge conflicts

- build test and run test your changes against at least one other platform, e.g: QEMU to check for multiplatform issues

In case this is of any value, there is a script here that will automatically generate pull requests emails for you based on branches matching what was mentioned above, it will also take care of CC'ing the people involved in the different patches:

https://github.com/ffainelli/misc-scripts/blob/master/gen-pull.pl

It still requires you to create an appropriate tag for the pull requests, though I might semi-automate that in the future, at least spawn an editor and offer some guidance, based on commit messages as to what should be in the pull request email/tag.
