[PATCH 1/3] MAINTAINERS: Remove Grant Likely

[PATCH 1/3] MAINTAINERS: Remove Grant Likely

[Grant Likely]

Unfortunately, I'm no longer to spend the time needed on maintainership.
It is time for me to step aside and pass maintainership to other
engineers. I'm not disappearing from Linux development, but it would be
irresponsible for me to hold onto a job that I am unable to do.

v2: Leave my name on devicetree core code maintainership. Rob NAKed that
    part of the patch. :)

[PATCH 3/3] MAINTAINERS: Refactor device tree maintainership

[Grant Likely]

Device tree bindings require a lot more attention than they used to.
We've got a group of volunteers willing to take over maintaining
bindings. This patch adds them to the MAINTAINERS file.

This group still needs to work out a process for maintainership and how
they are going to work together. I recommend that they set up a shared
tree on git.kernel.org that they each have commit access to similar to
the tip tree or the arm-soc tree, but it is up to them.

Perhaps it is time to also place the official repo
of the Device Tree Compiler on git,kernel.org as well?

Other opinions?

I'm fine with that. I can't say I'm excited about options like github.

Sounds good to me.

Now that I'm no longer at IBM, and don't have the associated
complications with their Legal department, I'd rather like to resume
having direct commit access to the master dtc tree.  So if we could
get Jon and myself, at least, push access to a tree on git.kernel.org,
that would be nice.

(Fwiw, I do have a personal dtc branch tree on github at
https://github.com/dgibson/dtc).

This seems a bit broad. Someone is going to get a whole lot of email
if this goes in, and it might confuse contributors on who is
maintainer of what under arch.

In fact, if things go well with the schema tool, it would be possible
to leave out the .dts files entirely as far as binding review goes.
The binding would be the important part and the .dts files would be
checked against that. That's something for the future though.

You can add me. I was not intending to step down.

What about creating an email alias for the group instead?

My own selfish desire is to easily separate emails for DT bindings and
DT core code. I suppose I could do that with a suffix on my email address.

It seems to work well for arm-soc where you have a group of maintainers
and don't necessarily know who is actively maintaining things. Not sure
if we want to timeshare like that, but it would give us the flexibility.

Noise to you is rock-n-roll to me. ;) It's only going to get harder if
lots of email to devicetree-discuss was getting dropped waiting for
moderator approval.

Yours is the harder problem since there is not really a way to use
kernel MAINTAINERS for dtc. Perhaps the kernel maintainer for dtc
could be "Send Your Patch Upstream <nobody@nowhere.com>".

One thing we didn't finish talking about was the question if this

Please no. When we move dts files out of the kernel, we will still need
to copy dt-bindings into the kernel. Also, I think we should move all
dts files out of arch subdirs and arrange by vendor or soc family. I'm
sure there are some cases that structure doesn't fit well, but there is
very little in a dts tied to a cpu architecture.

No as in: no don't put *.dtsi files into include/dt-bindings; or: no, do
not duplicate the motherboard file?

It you meant the latter, this is exactly what I wanted to say: I don't
want to do that, but there's no way of avoiding it right now.

And when would this happen? Don't get me wrong, I'm in favour of doing
this as well (I really don't want to push all 15-or-so DTSes for all the
different models and SMMs I have into the kernel)

I couldn't agree more. So:

<root>/include/dt-bindings/vendor/*?
<root>/dts/vendor/*?
<root>/of/vendor/*?
<root>/dt/vendor/*?
<root>/drivers/of/vendor/*?

Don't put *.dtsi into include/dt-bindings, I believe.

I think the solution is to introduce some new shared/common location for
shared/common *.dtsi files, into the kernel tree, in the interim.

When *.dts move out of the kernel, this common location can simply be
consumed as part of the DT tree re-organization.

Or perhaps, we could move *.dts around in the kernel to match the
proposed DT tree structure before that point in time?

FWIW I can easily handle any transformation as part of the automated
extraction into the device-tree.git. If it can expressed as a sed script
then so much the better, e.g. the current rules are
http://xenbits.xen.org/gitweb/?p=people/ianc/device-tree-rebasing.git;a=blob;f=scripts/rewrite-paths.sed;h=f7a157d1b486bac058f50e42cf7bedc8630e54ff;hb=HEAD.
If it gets too complicated for sed I can always switch to something
else.

I'm already pending a complete rebuild of the export to add in the
Documentation/devicetree/bindings sub tree but since it takes an age to
run I was waiting for the output of this conversation before kicking
that off.

I'd doubt we could completely script this with a generic rule without a
bunch of manual transformations. So I think either restructuring in the
kernel or when we move them out of the kernel makes more sense. We know
the problem is coming, but it is not yet a major, pressing issue.

OTOH, you could see how far you get by putting dts files in directories
by their board level compatible string vendor and put any include files
where ever they are included from. Of course, that is just my proposed
layout. I haven't heard any opinions on that layout.

Right. The advantage of scripting, even if that script is just a big
long list of manual rules, is that we can preserve the history from
linux.git in device-tree.git, so git annotate etc say something useful.

But if I'm going to write a big long list of such rules I'd like to only
do the bulk of the work once, so we need to decide on the layout first.

I don't really have a strong opinion on the layout myself, I'm happy to
implement whatever works for people.

The board level compatible string vendor is the top-level compatible,
right? e.g.:
        / {
                model = "Calxeda Highbank";
                compatible = "calxeda,highbank";
"calxeda,highbank" in this case. So you propose s|,|/| on that so the
file ends up in calxeda/highbank.dts?

For the included ecx-common.dtsi I think you are proposing to find all
the files which include it and then find the
deepest-common-subdirectory? In this case the other include is
ecx-2000.dts which is compatible calxeda,ecx-2000
(->calxeda/ecx2000.dts) so the common subdir is calxeda and dtsi would
become calxeda/ecs-2000.dtsi. That works, I should probably have picked
an example which didn't rely on files you are so involved with in case
there is a selection bias at work ;-)

Well, I was thinking just taking the vendor name and keep the existing
filename, but getting some consistency in filenames would probably be
good as well.

Yes, Calxeda stuff is obviously a simple example, but I don't think we
have any/many examples of includes across SOC vendors. Where things
breakdown are 3rd party boards. Do those go in the board or SOC vendor
directory? I'd vote for SOC vendor dir to keep the include structure
simple. That may still have issue if there are includes for
daughterboards which support multiple vendors' SOCs.

That layout sounds pretty reasonable. Are all those patches underneath
dt/ or is calxeda/ a top-level directory?

I guess that means that common files like skeleton.dtsi will simply end
up at the top-level (or in "top-level" dt/). That's probably fine.

I'd like the filenames to stay the same; to some degree I consider that
part of the DT ABI. At least for Tegra, and I think most/many other SoCs
follow this scheme..., we have named the files ${soc}-${board}.dts, and
made sure that the ${soc} and ${board} values match U-Boot's values, so
U-Boot can just "load mmc 0:1 ${soc}-${board}.dts" and hence use the
exact same U-Boot script for all Tegra boards (and potentially for any
board that defines ${soc} and ${board}, and doing that is easy).

So in the end I rebuilt with the existing transformation plus rewirting
Documentation/devicetree/bindings/ onto Bindings. I've pushed the new
branches to
        
        http://xenbits.xen.org/gitweb/?p=people/ianc/device-tree-rebasing.git
        git://xenbits.xen.org/people/ianc/device-tree-rebasing.git

In keeping with the name this means that the master and upstream/dts
branches have been rebased and so updates will be non-fastforwarding (as
has the internal filter-state branch). As you would expect the tags have
all changed as well.

These sorts of more complicated transformation aren't really feasible to
implement in the current automatic conversion process. It tries to
retain full history for the affected files (so git annotate/log/etc are
useful) which is OK for rewriting based solely on the path but once you
have to inspect the actual contents it gets more complicated and
significantly slower (since git rewrite-branch has to checkout every
tree, even without this it takes 2 days or so to convert).

These conversions would be better off done either as a second, probably
also automated, shuffling after (perhaps immediately after) we cut over
to using device-tree.git as the primary home.

If we end up doing some restructuring while these files are still in the
kernel I think I can still cope with that.
