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

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/[email protected]

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

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.

Subject: [PATCH net-next v2 2/5] 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.

+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.

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.
