Thanks for testing my patches.
On APM X-Gene Mustang platform, power off circuit is controlled by firmware.
It requires a firmware update to support power off feature.
May I ask what firmware version you're running on?

Just want to confirm you are booting in boot strap mode and had
SLIMpro firmware updated to 1.15.12 as well.
To check this, you should see this message in boot loader.

Slimpro FW:
        Ver: 2.4 (build 01.15.12.00 2015/05/20)

I tested on a Mustang A3, this works just fine.

Tai worked with me offline. For reference, this requires an updated
SlimPro firmware in addition to the u-boot update. Verified it works
for me after the update, so:

Hi,

It's unclear to me what you want to happen to these patches. They are
sent to a long list of to-recipients, one of which is arm@kernel.org. In
general, specify the person you want to take action on the patch in to
with the rest on cc.

We generally ask that patches first go to the subarch maintainers,
and they in turn send it on to us (either through a pull request or
by sending the patches to be applied). In the case of X-Gene, there is
no general platform maintainer so we keep getting patches from various
engineers at APM and it's unclear to us what your intentions are.

I'd prefer to see one (to start with) person in charge of these (i.e. one
maintainer from the APM side). Please add that person to the MAINTAINERS
file as well.


Thanks!

Is there an owner for all DT node files? Is that Catalina as he is
owner for ARM64 arch folder?

Are you suggesting that we have one person to start an GIT with
kernel.org to keep all these misc ack'ed patches for X-Gene (APM) that
don't seems to have an maintainer/home. Then request an pull by you?

Thanks,

The ARM64 DT changes get merged through arm-soc, i.e. they get sent to
arm-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org by the platform maintainers and picked up by us from
there (Arnd, Kevin or myself).

Pull requests are convenient for us, but if it's just a patch or two,
sending them directly in email is fine as well.

What I want to avoid is a large number of people sending us patches
directly, which is why we ask for platform maintainers to coordinate
and aggregate patches to send on to us. That way we have one person
down the chain that we knows how we want the code delivered, and that
can do a round of reviews before we get it.


Thanks!

If there is an chance in pulling this power off/reset patches for
4.2-rc4, can you pull in as patches? Otherwise, we will go the GIT
pull request.

We will get an GIT setup up for this and Duc Dang will contact you for
pull request when ready.

We can definitely pick them up and queue them for 4.3 (see below). We
normally want the bulk of patches before -rc4/5, but we take smaller
updates closer to the merge window as well.

Ok, sounds good. If you have people in the bay area that need PGP keys
signed for this, I'd be happy to help.

As far as the current DT patches, there's been several sent by
different people. Please aggregate them into one patch series and send
that (as git send-email is fine) to us to queue for 4.3.


Thanks!

We are debating whether we should setup a company server (where we can
have full control about storage, user permissions, backup, ...) or
just use github.com to host our X-Gene kernel tree.

Github seems already provide everything we need for a public source
tree. Per your experience, what is your (and probably other
maintainers) reference in git hosting server? Is there any
inconvenience or difficulty for the maintainers to pull/merge code
from Github versus from a company server?

Thanks!

Hosting on github is fine with us in general. We do prefer to get
signed pull requests in particular when they come from other sources
than kernel.org, mostly because there's another third party involved in
hosting the repo and by using signed tags there's less room for anyone
to do bad stuff with the repository without someone noticing.

If you host on github, please still use native git pull requests and not the
ones that github provides via the web interface.

Note however, that given the total volume of patches there's no strong need for
you to have a public repo just to send code to us -- we're happy applying
patches at the volumes we're currently looking at. I can imagine other reasons
for why you would like to have a public repo though.


Thanks,

-Olof

Thanks for the information, Olof.

We are setting up a public repo on Github. I will make sure that
native git pull request is used.

I will need your help in signing the PGP key when the repo is ready.

Hi Olof,

I have APM X-Gene git ready on github. According to your response
above, I need to
send a signed pull request. I created a PGP key on public server
(https://pgp.mit.edu/pks/lookup?search=duc+dang&op=index) and signed the tag on
APM X-Gene tree with my key.

Please let me know if I need anything else before sending the git pull
request to you.
My key is not signed by any maintainer yet, would you mind to arrange some
time next week to meet and help sign my key as well?

Yeah, I can do that, and you can get more signatures at Linaro Connect
in case you're attending.

(let's sort out details off-list).
