This is an initial series for supporting Socionext UniPhier SoCs,
based on ARM Cortex-A9, mainly used for digital TVs, video recorders, etc.
Masahiro Yamada (4):
ARM: UniPhier: add basic support for UniPhier architecture
ARM: multi_v7_defconfig: enable UniPhier SoC family
ARM: dts: UniPhier: add support for UniPhier SoCs and boards
MAINTAINERS: add myself as ARM/UniPhier maintainer

1.9.1
Initial commit for a new SoC family, UniPhier, developed by
Socionext Inc. (formerly, System LSI Business Division of
Panasonic Corporation).
This commit includes a minimal set of components for booting the
kernel, including SMP support.

Applied all four patches, to the next/soc, next/defconfig, next/dt and
next/soc branches respectively.
Welcome as our latest new maintainer. In the future, please send
any follow-up patches for the architecture specific code to
[email protected] in addition to the normal recipients, once you
consider them ready to be applied.

Thanks!
I can see them.

Please teach me a little more because I am not experienced enough
in this community.
I checked MAINTAINERS, but I could not find [email protected].
Is it documented somewhere?
I found ARM SUB-ARCHITECTURES entry in that file, but it does not mention
the responsible individuals.
(I assume, you and Olof are the ones.)
ARM SUB-ARCHITECTURES
L: [email protected] (moderated for non-subscribers)
S: Maintained
F: arch/arm/mach-*/
F: arch/arm/plat-*/
T: git git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git
I have one more question.
Are you receiving pull requests from each sub-arch maintainer?
Or should every patch be submitted to [email protected] and
applied by you (or other ARM-SoC maintainers)?
I have not earned enough reputations in this ML, so I know
it is too early for me to handle pull-reqs.
I understand the general development process of Linux, but
the maintainership of the ARM-SoC subsystem looks more hierarchized, so
I just want to know its development process correctly.

We normally only take patches from subarch maintainers that know who
we are and how it works, but we don't want to be Cc'd on every single
patch, so we don't have an entry in MAINTAINERS directly.

No worries, if you are unsure you can always ask us on the mailing
list or on the #armlinux channel on irc.freenode.net.
If you have more than a few patches at once, we'd always appreciate
a pull request, for a couple of patches, emails to [email protected] plus
linux-arm-kernel are fine as well.
When you do pull requests, please split them up according to larger
topics, e.g. send dts changes separately from code changes, and
separate bug fixes, cleanups and new feature support.
Often when you add a new driver, that will require sending the driver
code to a subsystem maintainer, and the dts changes to us. If everything
goes well, your DT bindings are both forward and backward compatible,
so they can get merged independently. If you ever have interdependencies
between them, talk to us first so we can find a solution.
For sending pull requests, it would be good to have a gpg key that
is signed by other well-known kernel developers. If you have such
a key, you can also request a kernel.org account to host a git tree
there, or you can host a git tree somewhere on your company's domain.
A public hosting service like github is not as good for us, but we
can deal with it when you are still ramping up your infrastructure.
Let me know if you need help finding kernel developers to sign your key.

Is a pull request from a kernel.org repo trusted more than the key itself? In
other words, if I sign my pull request with a trusted key, why would the git
repo location make any difference?

The main advantage is higher confidence I have in your pull request if I
don't look at the signature, because I can assume that someone else already
did when you got your account.

For now, I am not handling many patches, so I will send them to the ML.
If I need to send pull-reqs someday, I will ask for help.
Many thanks!!
