Sending patches to upstream kernel

1. You want to upstream these patches:

68e5c4b64765 ASoC: tegra: Add RT5631 machine driver
2bac54936f27 ASoC: dt-bindings: tegra: Add binding for RT5631

2. Create patches

# git format-patch -v1 --cover-letter -2 68e5c4b64765

Now you have these files:

v1-0000-cover-letter.patch
v1-0001-ASoC-dt-bindings-tegra-Add-binding-for-RT5631.patch
v1-0002-ASoC-tegra-Add-RT5631-machine-driver.patch

3. Check patches

# ./scripts/checkpatch.pl --strict v1*

If there are errors and warnings, fix them and go back to 1.

4. Open v1-0000-cover-letter.patch in text editor. Fill the SUBJECT
   and give a short description, telling what these patches are doing
   and why they are needed.

5. Get a list of email addresses to whom send the patches.

# ./scripts/get_maintainer.pl v1*

You'll get this list:

You are interested in maintainers, mailing lists and everyone who are directly related
to the patches. Ignore others. Hence you're interested in:

You may add me to the list since I helped you with the patches.

6. Send patches

I'll use my Gmail for example:

# git send-email --smtp-server=smtp.gmail.com --smtp-user=digetx@gmail.com --smtp-encryption=tls --smtp-server-port=587  --suppress-cc=all --to 'Thierry Reding <thierry.reding@gmail.com>' --to 'Jonathan Hunter <jonathanh@nvidia.com>' --to 'Stephen Warren <swarren@nvidia.com>' --to 'Mark Brown <broonie@kernel.org>' --to 'Takashi Iwai <tiwai@suse.com>' --to 'Jaroslav Kysela <perex@perex.cz>' --to 'Rob Herring <robh+dt@kernel.org>' --to 'Svyatoslav <clamor95@gmail.com>' --to 'Ion Agorria <ion@agorria.com>' --to '' --to 'Dmitry Osipenko <digetx@gmail.com>' --cc 'alsa-devel@alsa-project.org' --cc 'devicetree@vger.kernel.org' --cc 'linux-tegra@vger.kernel.org'  --cc 'linux-kernel@vger.kernel.org' --confirm=always v1*

Use "--to" for people and "--cc" for mailing lists. 

Git will print out list of email recipients and files to send, check that everything looks okay.
Git asks "Send this email? ([y]es|[n]o|[e]dit|[q]uit|[a]ll):", answer "all".

Enter your email password and wait till all patches are sent out by git. Done.

If everything went okay, you'll see your patches in patchwork of the mailing lists:

https://patchwork.ozlabs.org/project/linux-tegra/list/
https://patchwork.kernel.org/project/alsa-devel/list/

7. Wait for review comments. Depending on a maintainer, it may take couple days, a week or more than a month. Be prepared
   that you may not get quick replies, just wait. If nobody answered for more than a month or two, go to 1 and send patches
   again.

8. If maintainer requsted to make changes, make them and go back to 1. Use "-v2" for `git format-patch ..` to bump version of
   the patches to v2.
   
9. Maintainer will answer you if everything is okay and patches are applied. Done.
