[PATCH net-next v2 0/5] Create a binding for the Marvell MV88E6xxx DSA switches

[PATCH net-next v2 0/5] Create a binding for the Marvell MV88E6xxx DSA switches

[Linus Walleij]

This shows the path we could take with this, deprecating the
weird external bus thing.

I don't know what to do about the irq lines with a pointless
type flag that should be onecell:ed.

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.

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/20231013-marvell-88e6152-wan-led-v1-0-0712ba99857c@linaro.org

[PATCH net-next v2 1/5] dt-bindings: marvell: Rewrite MV88E6xxx in schema

[Linus Walleij]

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?

[PATCH net-next v2 2/5] dt-bindings: marvell: Add Marvell MV88E6060 DSA schema

[Linus Walleij]

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.

+
+description:
+  The Marvell MV88E6060 switch has been produced and sold by Marvell
+  since at least 2010. The switch has one pin ADDR4 that controls the
+  MDIO address of the switch to be 0x10 or 0x00, and on the MDIO bus
+  connected to the switch, the PHY:s inside the switch appear as
+  independent devices on address 0x00-0x04 or 0x10-0x14, so in difference
+  from many other DSA switches this switch does not have an internal
+  MDIO bus for the PHY devices.

+    const: marvell,mv88e6060
+    description:
+      The MV88E6060 is the oldest Marvell DSA switch product, and
+      as such a bit limited in features compared to later hardware.

[PATCH net-next v2 3/5] ARM: dts: marvell: Fix some common switch mistakes

[Linus Walleij]

Fix some errors in the Marvell MV88E6xxx switch descriptions:
- The top node had no address size or cells.
- switch0@0 is not OK, should be switch@0.
- port@a is not normal port naming, use decimal port@10.
- The ports node should have port@0 etc children, no
  plural "ports".

This serves as an example of fixes needed for introducing a
schema for the bindings, but the patch can simply be applied.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

This is not quite correct. For marvell,mv88e6085 and marvell,mv88e6250
there is one MDIO bus, which can be used both internally and
externally.

For marvell,mv88e6190, there are two MDIO buses. This one is used only
internally, and 'mdio-external' is connected to pins for external use.

Also, its not used to access switch ports. It is used to access PHYs
which can connected to switch ports.

It is a Fast Ethernet switch, so it will not be using Reduced Gigabit
MII. 'rev-mii' would be a better choice.

label = "cpu" is deprecated, so you probably don't want it in an
example.
