[PATCH v2 0/5] Add support for BeagleBone Green Eco board

[PATCH v2 0/5] Add support for BeagleBone Green Eco board

[Kory Maincent]

SeeedStudio BeagleBone Green Eco (BBGE) is a clone of the BeagleBone Green
(BBG). It has minor differences from the BBG, such as a different PMIC,
a different Ethernet PHY, and a larger eMMC.

Also update the omap.yaml binding to include missing compatible strings
that were previously undocumented.

[PATCH v2 1/5] arm: dts: omap: Remove incorrect compatible strings from device trees

[Kory Maincent]

Several device trees incorrectly included ti,am335x-bone-black or
ti,am335x-bone in their compatible lists without including the
corresponding bone-black-common or bone-common device tree files.
Remove these incompatible strings to fix the inconsistency.

this looks like too much cleanup, also according your omap.yaml stuff,
ti,am335x-bone-green should still be included.

"bone variant" sounds like some shortand or nickname. Are the boards not
called "beaglebone green" and "beaglebone black"? Whatever about the
compatible, the description should use the full name I think.

we have an enum below it listing all those variants. So "variants"
makes sense here, but better "TI Beaglebone variants"

Yes, this was a comment on calling it a "bone", when that's not what the
boards are called in their marketing material etc, not objecting to the
word variant.

What is the convention here? "beagle" is a vendor, so not sure why
this continues to be "ti". The owner of the brand for this board is
"The BeagleBoard.org Foundation". Not sure if it is reasonable to fix
this.

This one is also "beagle", not "ti".

I'm not sure this is really needed. There is some desire to fall-back
to a building block level of functionality around these derivatives of
"BeagleBoard.org BeagleBone", including compatibility with the
expansion headers, but I don't think that will happen at this level.
In u-boot, it is possible to make the determination to utilize a
less-complete devicetree, but it seems impractical here.

What are the objections to just listing these all as TI AM33 based platforms?

"beagle"

This is a Seeed Technology Co., Ltd. board that licenses the
BeagleBone brand from the BeagleBoard.org Foundation, so "seeed", not
"ti".

> > +              - ti,am335x-pocketbeagle

Not sure why this one is repeated. Also, it very much begs the
definition of being a BeagleBone derivative outside of usage of the
PMIC.

There are lots of derivatives of BeagleBoard.org BeagleBone Black and
falling back to a compatible makes some sense, but I don't think it is
of practical benefit here the way things have worked out. The smarts
have to be in the bootloader based off of the board IDs and the kernel
is just going to do what it is told.

Now, if we had some practical overlays performed by the kernel, this
would all make some sense as patches between these variants provide
useful fallback operation, but this is otherwise confusing. I
appreciate the credit given to BeagleBoard.org for them being
variants, but this really isn't the place.

Note that this one is correct to be "sancloud", who licenses the
BeagleBone brand from the BeagleBoard.org Foundation.

Do we really need these "bone variants" split out from the above
list of TI AM33 based boards? We don't do that for any of the other
boards, you get a SoC and a Board compatible, every classification
in-between is just unneeded.

As omap maintainers prefer. I did that to have the least amount of change in
the devicetree. We could have U-boot using these compatible but after a quick
check it seems not.

I agree with both. The intermediate compatibles that TI in particular 
went crazy on have proven to be not useful. However, between having to 
fix existing .dts files and keeping them, I would just keep them.

We have something like this for the Pandaboards models. But
e.g. the i.MX Udoo Neo stuff which just differs in what is populated
does not have this. So I do not see a clear pattern. It could be useful
for userspace to store some board-specific configurations which might be
the same for a family of boards. So if people shout out loud that these
are needs, lets kep them.

[PATCH v2 4/5] arm: dts: omap: Add support for BeagleBone Green Eco board

[Kory Maincent]

SeeedStudio BeagleBone Green Eco (BBGE) is a clone of the BeagleBone Green
(BBG). It has minor differences from the BBG, such as a different PMIC,
a different Ethernet PHY, and a larger eMMC.

Signed-off-by: Kory Maincent <kory.maincent@bootlin.com>
---

Changes in v2:
- Used generic pmic node name.
- Add regulator prefix to fixed regulator node name.
- Add the compatible to omap.yaml binding

Do you mean that the binding change should be in another patch?

Usually binding changes are in a separate patch. Maybe you can merge it
with Patch 2. The lonely enum looks a bit strange there, so if these
things are merged, it will look more natural.

Yes, you have a binding change hidden away in a dts patch.

Yes, as requested by checkpatch and documented in DT submitting patches.
Your question above, suggests you did not run checkpatch, so please
confirm you run it before posting new versions.

Why omap2plus_defconfig? OMAP3 and newer are all ARMv7 and
boards with those can/should use multi_v7_defconfig.

OMAP1 and OMAP2 are the only devices that cannot use multi_v7_defconfig
as they are not ARMv7. So I'd almost recommend we rename
omap2plus_defconfig to just omap2_defconfig to avoid more confusion.
Then we would have:

OMAP1:  ARMv4/5: omap1_defconfig
OMAP2:  ARMv6:   omap2_defconfig
OMAP3+: ARMv7:   multi_v7_defconfig

Any issue with that I'm missing?

if there are enough drivers enabled there, it would work, but it is not.
So there need to be a bunch of patches to add the missing stuff.
omap2plus_defconfig is there and support for boards are added.

So I think until multi_v7_defconfig is really usable for OMAP3+, we
should stick with the name omap2plus_defconfig and add stuff.
If we rename omap2plus_defconfig to omap2_defconfig, we should imho
disable OMAP3/4/5 there to avoid confusion.

Andreas

Yes multi_v7 is still missing stuff for some boards we want to
support, and we are working on adding those needed modules now.

We won't get feature parity in multi_v7 if we keep adding new
boards to the old omap2plus_defconfig. For this patch series
how about we add support to both defconfigs?

Yes, that was part of the plan, right now these SoCs are enabled
in both configs, so new boards often get enabled in one or the other
but rarely both.

Keeping the more specific defconfigs around is handy as they're much
smaller and therefore faster to build, but I do agree that the
multi_vX_defconfigs should also work.
