[PATCH v2] mips: dts: ralink: mt7621: add cell count properties to usb

[Justin Swartz]

Add default #address-cells and #size-cells properties to the
usb node, which should be suitable for hubs and devices without
explicitly declared interface nodes, as:

  "#address-cells":
    description: should be 1 for hub nodes with device nodes,
      should be 2 for device nodes with interface nodes.
    enum: [1, 2]

  "#size-cells":
    const: 0

-- Documentation/devicetree/bindings/usb/usb-device.yaml

This version of the patch places the properties according to
the order recommended by:

   Documentation/devicetree/bindings/dts-coding-style.rst

Drop these three lines, this explanation would be after --- line as
information about the changes from v1.

Please keep the empty lines. It's easier to read. I don't see anything on
the Devicetree Sources (DTS) Coding Style that would restrict this.

The reason I removed them was due to the SoC DTSI example shown in [1]
lacking empty lines between properties, but then using them instead as
visual separation between properties and child nodes, or at least that's
how I understood it when I looked at it.

Personally, I prefer the look of the SoC DTSI example - but I don't mind
recreating the patch set with the empty lines between the properties 
left
entact.

As there is a mix of property spacing and ordering styles in mt7621.dtsi
already - what is the consensus on what a node in this file should look
like?

I also don't mind following that pattern and cleaning up the whole dtsi
according to that if it'll save us all time and energy in future.

There's no precise spacing style I maintain here. I simply group together
properties that describe a single attribute, and separate those that
describe different attributes.

If you'd like to improve the ordering style of the MT7621 device tree
sources accordingly with
Documentation/devicetree/bindings/dts-coding-style.rst, I'd be happy to
review those patches.

I'll recreate v3 accordingly.

[PATCH v2] mips: dts: ralink: mt7621: add cell count properties to usb

[Justin Swartz]

Add default #address-cells and #size-cells properties to the
usb node, which should be suitable for hubs and devices without
explicitly declared interface nodes, as:

  "#address-cells":
    description: should be 1 for hub nodes with device nodes,
      should be 2 for device nodes with interface nodes.
    enum: [1, 2]

  "#size-cells":
    const: 0

-- Documentation/devicetree/bindings/usb/usb-device.yaml

This version of the patch places the properties according to
the order recommended by:

   Documentation/devicetree/bindings/dts-coding-style.rst
