[PATCH v2 0/3] Add support for the Pine64 PinePhone Pro phone

[PATCH v2 0/3] Add support for the Pine64 PinePhone Pro phone

[Tom Fitzhenry]

PinePhone Pro is a RK3399 based phone produced by Pine64.

Add a basic DTS for it. This is a working base that will allow myself and
others to add more nodes.

Changes since v1:
* Simplified the DT to a minimal base.
* Introduced the RK3399-T OPPs.

[PATCH v2 1/3] arm64: dts: rockchip: Add RK3399-T opp

[Tom Fitzhenry]

From: Samuel Dionne-Riel <samuel@dionne-riel.com>

These tables were derived from the regular RK3399 table, by dropping
entries exceeding recommended operating conditions from the datasheet,
and clamping the last exceeding value where it made sense.

Do we really need to duplicate the whole OPP table of rk3399-opp.dtsi
just to disable a few top opp## entries?

This will make it more annoying to add PVTM/eFuse leakage based voltage
selection support later on, because then there would have to be identical
multi-level operating points across multiple files. And that sounds like
a LOT of dupplication for little benefit.

Also Pinephone Pro has RK3399S not -T. RK3399 seems to be RK3399 selected for
low leakage (values I've seen from eFuses indicate the leakage is half that of
RK3399 available in Pinebook Pro)

I'd suggest just adding references to select operating point nodes that
are "too much" and disabling them with status = "disabled". This
can be done from the pinephone device tree file directly.

Otherwise we'll eventually end up with several files containing
something like this [1] and only differing in absence of some opp## nodes
and not their actual useful content.

The vendor (PINE64) asked me to make these changes while stating specifically
that the Pinephone Pro uses the RK3399-T. Though earlier units and current
batches use the RK3399[s], the design was reportedly made with the RK3399-T
in mind.

The device was also designed to use the OPP from the RK3399-T on RK3399[s]
for the designed thermal operation of the device, reportedly.

As to why this is a new file? I have assumed it would be preferable since
this is how it was done for the "OP1" variant of the RK3399. I will defer to
the Rockchip and ARM maintainers to determine which way is better.

I will note that in practice I agree here.

[PATCH v2 3/3] arm64: dts: rockchip: Add initial support for Pine64 PinePhone Pro

[Tom Fitzhenry]

This is a basic DT containing regulators and UART, intended to be a
base that myself and others can add additional nodes in future patches.

Tested to work: booting from eMMC, output over UART.

This is derived from a combination of https://gitlab.com/pine64-org/linux
and https://megous.com/git/linux.

Hi,

I was surprised to see this series, and this patch especially.
An almost ready to submit version of this patch with considerably more 
functionality has been sat around for a while but unfortunately never sent [1].

Creating a minimal patch to just finally get the PinePhone pro into mainline is 
not a bad idea, but as it stands I'm not fully on board with this patch.

According to the link below (and my own knowledge of PPP development) Kamil is 
the original author of this patch, both Kamil and Martijn created the initial 
version of the devicetree. Given that you're using their work as a base, Kamil's 
authorship should be respected in the patch you submit.

Their original patch [2] contained SoBs from them and Martijn, those are both 
missing below. Both of their signed-off-by tags should be added before this 
patch hits the mailing list, and the same for Ondrej. The order also seems wrong 
(Ondrej should be last before you).

Support for the volume keys, accelerometer, magnetometer, GPIO LEDs, 
touchscreen, modem codec and audio support are all missing here, but they're 
included in the patches you referenced. In their current state (see Martijn's 
commit [1] or my 5.19 rebase [3]) the DT for these components has been worked on 
by several people, tested by the larger user community, and are already 
supported in mainline. It seems strange not to include them and just leads to a 
bunch of extra busywork to add them back later. It's easy enough to drop any of 
these nodes during review if they become an issue.

With that being said, I've left some feedback below, with it addressed and the 
authorship/SoB situation sorted out:

Reviewed-by: Caleb Connolly <kc@postmarketos.org>

Alternatively, I'd be more than happy to review a new revision with the 
aforementioned nodes re-included.

Kind Regards,
Caleb

Firstly, thank you for your review!

I'm not sure why that other patch series has never been submitted. It 
was prepared 3 months ago (unbeknownst to me, at the time of v1), but 
since then has not been submitted.

I would feel uncomfortable submitting that patch series, since I am not 
familiar with parts of the full DT. In time I intend to be, but for now 
I think we'd benefit from having a base DT mainlined, on top of which we 
can iterate and parallelise.

I agree authorship is important, and thus Kamil, Martijn and Megi are 
listed as Co-developed-by in this patch.

Yes, this patch's acceptance is blocked until all Co-developed-by 
authors (Kamil, Martjin, Megi) provide their Signed-off-by to this patch.

To keep this patch series light and easy-to-review, I'd be keen to keep 
it as small as possible for now. This DT is >18 months old out-of-tree 
(across multiple repos), so I think this minimal DT being mainlined is 
an improvement over the status quo.

The existing work that the community has done will still be useful, 
albeit in future patch series. This DT just allows that future work to 
be done iteratively, and in parallel.

Thank you for your comments, I appreciate your review! I will ensure v3 
addresses those.

To be clear, by authorship I mean literally the author of the patch, the 
previous patch in this series was created by Samuel and you left his authorship 
intact - it has "From: Samuel Dionne-Riel <samuel@dionne-riel.com>" at the top, 
so when a maintainer picks it up and it ends up in Linux, anyone looking at it 
will see that he was the author of the patch.

This patch is from you, there is no From: tag overriding it, and the diffstat in 
your cover letter shows you as the author. Whilst you have obviously made some 
heavy changes to this patch, it isn't your original work as you state yourself 
in the commit message. Authorship should be attributed to Kamil as they are the 
author of the earliest version of this patch we have.

You should obtain SoBs from Co-developers /before/ sending this patch upstream, 
this indicates that everyone is on board and that the patch has some sensible 
history. The mailing list isn't the place to ask your co-developers to sign off 
a patch after you've made extensive changes to it.

I missed the following points in my original email:

Please read the documentation on modifying patches [1] as it applies here, and 
add a comment before your SoB explaining your changes, something like

[tom: strip down to minimal booting DT for initial support]

This way the history of the patch is preserved properly for anyone looking back 
at it in the future. In a similar vein, replace the external git links with 
links to exact commits so they don't degrade over time.

fwiw, a few extra nodes now is a lot easier to review than a bunch of individual 
small patches later. But yes, better to get this done in some form than not at all.

definitely, it'll be nice to start to see some upstream story for the famed 
"linux phone" ;)

Looks like there's some confusion here, that I may have added to at some
point by a bit of patch squashing, and some SoB tag creativity. ;)

Let me try to clear it up a bit, since it's my squashed patch this discussion
and this submission is based around. Patch [2] you're linking to is not an
original patch by Martijn or Kamil.

It's just a squashed bunch of patches that I took from a secret repo that Kamil
shared with me once upon a time, so that I can help with kernel development and
camera support for Pinephone Pro about a year ago, when it was still a secret
thing.

*AFAIK*, original patches in the secret repo were never published by authors,
but only through my squashed patch from my kernel tree. All the prior work seems
to be either in unlisted git repos, or in login gated git repos.

So hereby I give my Signed-off-by: Ondrej Jriman <megi@xff.cz> for the patch
[2] this submission by Tom was developed from, stating that to the best of my
knowledge:

1) Original author is Martijn Braam and "Fuzhou Rockchip Electronics Co., Ltd".
   Kamil Trzciński extended the Martijn's original DT with some things that are
   mostly stripped off in this submission, other than a few oneliners and the
   gpio power key node. I also have maybe one or two lines in this submission.
2) Original work was published under MIT or GPL2.0+
3) Original work is missing copyright header from Rockchip and any SoB on the
   patches. I have added the SoB for Martijn/Kamil myself without asking them.
   Sorry for that. And I guess this is the source of some confusion here, too.

That should cover the requirement b) of "Developer’s Certificate of Origin 1.1"
which should be all that's necessary.

So now that we have all the needed SoB for the base patch, and Tom already has
SoB for his modifications, all the Co-developed-by are in place, and copyright
notices from original authors are untouched in the code, except for Rockchip,
the way forward should be to re-add missing:

  Copyright (c) 2021 Fuzhou Rockchip Electronics Co., Ltd

to the code and add my SoB to the commit message. That should make the
provenance of this code clear and properly accounted for.

SoB from Martijn would be nice to have, just to reassure about the Rockchip
copyright, which I assume authored the Android factory kernel code/DT. But I'm
presonally quite sure this code is MIT/GPL2.0+, regardless.

------

If you want more details, then here is the original patch series from the secret
repo: https://megous.com/git/linux/log/?h=ayufan-secret/pinephone-pro

Martijn's original patch as taken over by Kamil is
https://megous.com/git/linux/commit/?h=ayufan-secret/pinephone-pro&id=9f1a4867c21a9fa88177bd0903bdc1d82e213310
It has Martijn's copyright and is published under GPL2.0+ OR MIT. This is the
earliest available code this all is based on.

It will sure have some history, too, given that almost all of rk818 node content
matches the decompiled Android factory image's device tree to the
T and that's like 50% of the code in this submission. :) That's where my guess
that the original patch is missing Rockchip's copyright is comming from.

Android DT was never published in code form for all I know. I guess that's what
we get for requiring DT be licensed under MIT license. Some Rockchip engineer
likely wrote half of this submission. Rockchip copyright is thus probably
missing from the patch. Decompiled DT here: https://megous.com/dl/tmp/01_dtbdump_rockchip,android.dts

Kamil seems to have these changes in this submission:

But you miss their SoB... Without them you should not send it. It does
not pass checkpatch, does it?

You add SoB based on original work. When you send a patch, it is
expected to be ready (so having correct DCO chain), not incomplete from
our process point of view.

Sorry, my bad. I see 
https://www.kernel.org/doc/html/latest/process/submitting-patches.html 
lists to use checkpatch. I had read this but had since forgotten. I will 
ensure future patches pass checkpatch.

Just gpio-keys like all sources are doing.

Schema requires generic naming. Either "key" or "key-0" or "key-power"

Interestingly, most DTS files in rockchip/ use a -regulator
suffix and none use regulator- prefix. And this is inconsistent
across the larger DTS tree, because outside of rockchip/ most
DTS use a prefix.

Checked by grep -R 'regulator.*{' | grep -v state-me

Can be a suffix. Just pick one pattern.
