Subject: [PATCH net-next v9 0/5] Create a binding for the Marvell MV88E6xxx DSA switches

The Marvell switches are lacking DT bindings.

I need proper schema checking to add LED support to the
Marvell switch. Just how it is, it can't go on like this.

Some Device Tree fixes are included in the series, these
remove the major and most annoying warnings fallout noise:
some warnings remain, and these are of more serious nature,
such as missing phy-mode. They can be applied individually,
or to the networking tree with the rest of the patches.

Thanks to Andrew Lunn, Vladimir Oltean and Russell King
for excellent review and feedback!

This latest version employs special compatibles in the
odd ABI device trees.

---
Changes in v9:
- Drop all the per-platform device tree fixes, instead send these
separately for Marvell and NXP platform trees to be applied through
the SoC tree.
- This means the bindings will yield robotized warnings. Ignore these,
and rely on platform maintainers to deal with the fallout.
Patches exists for the majority of the problems, see v8.
- Link to v8: https://lore.kernel.org/r/[email protected]

Changes in v8:
- Restore ALL original switch node names in the Turris Mox, not just
the top one. Put a comment above each not to change the node name.
- Add a special compatible for the Turris Mox switches, so that we
can apply special rules for these ABI nodes.
- Add quirks to the bindings to deal with the special node names
so we don't get unsolicited warnings about them from the checks.
This is done so that people will not come and "fix the DTS files"
so they break. We only have serious warnings after this.
- Add the quirks and updates to the nodes into separate patches
for review.
- Link to v7: https://lore.kernel.org/r/[email protected]

Changes in v7:
- Fix the elaborate spacing to satisfy yamllint in the
ports/ethernet-ports requirement.
- Link to v6: https://lore.kernel.org/r/[email protected]

Changes in v6:
- Fix ports/ethernet-ports requirement with proper indenting
(hopefully).
- Link to v5: https://lore.kernel.org/r/[email protected]

Changes in v5:
- Consistently rename switch@n to ethernet-switch@n in all cleanup patches
- Consistently rename ports to ethernet-ports in all cleanup patches
- Consistently rename all port@n to ethernet-port@n in all cleanup patches
- Consistently rename all phy@n to ethernet-phy@n in all cleanup patches
- Restore the nodename on the Turris MOX which has a U-Boot binary using the
nodename as ABI, put in a blurb warning about this so no-one else tries
to change it in the future.
- Drop dsa.yaml direct references where we reference dsa.yaml#/$defs/ethernet-ports
- Replace the conjured MV88E6xxx example by a better one based on imx6qdl
plus strictly named nodes and added reset-gpios for a more complete example,
and another example using the interrupt controller based on
armada-381-netgear-gs110emx.dts
- Bump lineage to 2008 as Vladimir says the code was developed starting 2008.
- Link to v4: https://lore.kernel.org/r/[email protected]

Changes in v4:
- Rebase the series on top of Rob's series
"dt-bindings: net: Child node schema cleanups" (or the hex numbered
ports will not work)
- Fix up a whitespacing error corrupting v3...
- Add a new patch making the generic DSA binding require ports or
ethernet-ports in the switch node.
- Drop any corrections of port@a in the patches.
- Drop oneOf in the compatible enum for mv88e6xxx
- Use ethernet-switch, ethernet-ports and ethernet-phy in the examples
- Transclude the dsa.yaml#/$defs/ethernet-ports define for ports
- Move the DTS and binding fixes first, before the actual bindings,
so they apply without (too many) warnings as fallout.
- Drop stray colon in text.
- Drop example port in the mveusb binding.
- Link to v3: https://lore.kernel.org/r/[email protected]

Changes in v3:
- Fix up a related mvusb example in a different binding that
the scripts were complaining about.
- Fix up the wording on internal vs external MDIO buses in the
mv88e6xxx binding document.
- Remove pointless label and put the right rev-mii into the
MV88E6060 schema.
- Link to v2: https://lore.kernel.org/r/[email protected]

Changes in v2:
- Break out a separate Marvell MV88E6060 binding file. I stand corrected.
- Drop the idea to rely on nodename mdio-external for the external
MDIO bus, keep the compatible, drop patch for the driver.
- Fix more Marvell DT mistakes.
- Fix NXP DT mistakes in a separate patch.
- Fix Marvell ARM64 mistakes in a separate patch.
- Link to v1: https://lore.kernel.org/r/[email protected]

Subject: [PATCH net-next v9 5/5] dt-bindings: marvell: Add Marvell MV88E6060 DSA schema

The Marvell MV88E6060 is one of the oldest DSA switches from
Marvell, and it has DT bindings used in the wild. Let's define
them properly.

It is different enough from the rest of the MV88E6xxx switches
that it deserves its own binding.

Subject: [PATCH net-next v9 4/5] dt-bindings: marvell: Rewrite MV88E6xxx in schema

This is an attempt to rewrite the Marvell MV88E6xxx switch bindings
in YAML schema.

The current text binding says:
WARNING: This binding is currently unstable. Do not program it into a
FLASH never to be changed again. Once this binding is stable, this
warning will be removed.

Well that never happened before we switched to YAML markup,
we can't have it like this, what about fixing the mess?

Subject: [PATCH net-next v9 2/5] dt-bindings: net: mvusb: Fix up DSA example

When adding a proper schema for the Marvell mx88e6xxx switch,
the scripts start complaining about this embedded example:

dtschema/dtc warnings/errors:
net/marvell,mvusb.example.dtb: switch@0: ports: '#address-cells'
is a required property
from schema $id: http://devicetree.org/schemas/net/dsa/marvell,mv88e6xxx.yaml#
net/marvell,mvusb.example.dtb: switch@0: ports: '#size-cells'
is a required property
from schema $id: http://devicetree.org/schemas/net/dsa/marvell,mv88e6xxx.yaml#

Fix this up by extending the example with those properties in
the ports node.

While we are at it, rename "ports" to "ethernet-ports" and rename
"switch" to "ethernet-switch" as this is recommended practice.

Subject: [PATCH net-next v9 3/5] dt-bindings: net: ethernet-switch: Accept special variants

Accept special node naming variants for Marvell switches with
special node names as ABI.

This is maybe not the prettiest but it avoids special-casing
the Marvell MV88E6xxx bindings by copying a lot of generic
binding code down into that one binding just to special-case
these unfixable nodes.
