[PATCH 0/5] Add gta04 board variants

[PATCH 0/5] Add gta04 board variants

[Marek Belisko]

This patch series completes the GTA04 device tree to describe all hardware
components that are on the different variants of the GTA04 boards.

Marek Belisko (5):
  arm: dts: omap3-gta04: Add missing nodes to fully describe gta04 board
  arm: dts: omap3-gta04: Rename gta04.dts to gta04.dtsi and add a4 model
  arm: dts: Add gta04a3 model
  arm: dts: Add gta04+b2 model bindings
  arm: dts: Add gta04+b3 model bindings

Re: [PATCH 1/5] arm: dts: omap3-gta04: Add missing nodes to fully describe gta04 board

[Joachim Eastwood]

Hi Marek,

You seem to add some DT nodes for hw that doesn't have drivers in
mainline. I think you should leave those out until the driver itself
is upstream and the bindings for it is documented.

The omap-pwm driver is not yet upstream and thus the bindings are not final.

I don't think any of the above devices have documented bindings so I
don't think it is a good idea to add the nodes now.

Any reason why you don't use OMAP_IOPAD macro for the I2C pins?

Re: [PATCH 1/5] arm: dts: omap3-gta04: Add missing nodes to fully describe gta04 board

[Dr. H. Nikolaus Schaller]

Hi Joachim,
is there some policy for only having nodes for existing drivers in DT files?

If I understand the device tree concept correctly, it should not describe drivers
(and hence nothing about the state of them being mainlined), but it should statically
describe the given hardware in a way that kernel and drivers can read it (or ignore).
And even other kernels can use it (because they run on the same hardware).

So unless there is an important reason not to have "currently unused" nodes
in the DT source/binary (loading time is IMHO neglectable), I would ask that we
can keep with the complete DT instead of splitting it up artificially and getting back
to the same status (because the hardware does not change over time).

Regarding bindings documentation I agree that it is a very necessary part of
each driver, i.e. documenting what the driver supports.

BR,
Nikolaus

I am not sure about that, better ask the DT maintainers.

There is however a policy that says new bindings should be reviewed
and documented.

The problem with the nodes is that the bindings may change when the
drivers/bindings are submitted to mainline and reviewed. I don't see
why you want nodes for hardware that right now obviously don't work
with mainline and if the bindings change it will churn and confusion
for the users.

One example is the omap-pwm driver. It should really have #pwm-cells
set to 3 and not 2. This driver is not upstream yet, because it
requires some files to move out of arch/arm. See
http://marc.info/?l=linux-omap&m=139903867022779&w=2 for the suggested
new bindings.

The normal case for new DT boards is to first submit nodes for the
hardware that is working in mainline and then update the DT with more
nodes for hardware as bindings are decided upon and drivers go
upstream.

Please don't top post.

Joachim Eastwood

Yes, it should describe hardware but that description should be
previously agreed and properly documented as was mentioned before.

I understand your motivation since it will allow you to not have to
maintain a patch-set for your downstream DTS changes but I would like
to ask you the opposite question. What's the benefit for the kernel
community to keep in a mainline DTS a bunch of device nodes with DT
bindings that have not been neither discussed nor documented?

Developers doing a board bring-up usually use the DTS in mainline as a
reference for their boards and having non-documented/agreed DT binding
on the upstream DTS will only bring confusion and frustration to them
IMHO.

We already have some issues with Device Trees (bindings that broke
backward compatibility, drivers implementing custom DT binding instead
of using standard ones, bindings that don't really reflect the actual
H/W, etc), please don't make this even more complicated to developers.

Thanks a lot and best regards,
Javier

Ok, it is a little a hen and egg problem - who should start with the documentation.
The device tree file, more or less describing what the hardware requirements
are. Or the drivers which describe what they support.

And you are right - these two ends must match and that can only be resolved by
discussions and negotiations between both ends.

Less patches to review individually. Just a single one instead.
But this might be a weak benefit.

Well, my experience (at least for the current status) is that in most times new
boards need new drivers and DT nodes anyways. But this might change.

Ok, then I think we will do the way as suggested and only submit DT nodes
for already existing drivers. Or submit new ones bundled with driver and
documentation patches.

Marek will update the patches anyways, so that they apply without errors.

Hmm at least the first patch won't apply:

Hunk #4 FAILED at 143.
Hunk #5 succeeded at 142 with fuzz 2 (offset -26 lines).
Hunk #6 succeeded at 287 (offset -26 lines).
Hunk #7 succeeded at 364 (offset -26 lines).
Hunk #8 succeeded at 433 (offset -26 lines).
Hunk #9 succeeded at 472 (offset -26 lines).
Hunk #10 succeeded at 485 (offset -26 lines).
Hunk #11 succeeded at 556 (offset -26 lines).
Hunk #12 FAILED at 720.
2 out of 12 hunks FAILED -- rejects in file arch/arm/boot/dts/omap3-gta04.dts

Can you please repost against let's say v3.16-rc1? Maybe also
check they apply cleanly against omap-for-v3.17/dt branch that
I just pushed out to:

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap omap-for-v3.17/dt

Thanks,

Tony
