[PATCH v5 0/2] usb: dt-bindings: ti,twlxxxx-usb: convert to DT schema

[PATCH v5 0/2] usb: dt-bindings: ti,twlxxxx-usb: convert to DT schema

[Jihed Chaibi]

This series converts the legacy TXT bindings for the TI TWL4030
and TWL6030 USB modules to the modern YAML DT schema format.

---
Changes in v5:
 - Split combined twlxxxx-usb binding into two dedicated files
   for TWL4030 and TWL6030 per maintainer feedback.
 - Used more accurate header file for interrupt macros.
 - Improved formatting in the examples.

Changes in v4:
 - This patch is split from larger series per maintainer feedback.
 - v3 link:
    https://lore.kernel.org/all/20250816021523.167049-1-jihed.chaibi.dev@gmail.com/
 - Removed i2c node as it wasn't required by the old binding file.
 - Updated node names to 'usb' and 'usb-phy' in the examples to follow
   generic naming conventions per the Device Tree specification.
 - Replaced raw interrupt values with standard defines for clarity.
 - Improved formatting in the examples for clarity and consistency.

Changes in v3:
 - No changes.

Changes in v2:
 - Added '#phy-cells' property to support PHY framework integration.

[PATCH v5 1/2] usb: dt-bindings: ti,twl4030-usb: convert to DT schema

[Jihed Chaibi]

Convert the legacy TXT binding for the TWL4030 USB module
to the modern YAML DT schema format. This adds formal validation
and improves documentation using a conditional schema.

Confusing. So first is CPU?

But furst is OTG?

After splitting the binding this should be rewritten. Drop description,
no need for free form text.

minItems: 1
items:
  - description: OTG for ...
  - description: foo bar and do not say it is optional because it is obvious from schema


Missing also removal of this device from the TXT binding.

Krzysztof

Redundant constraints and description.

  items:
    - description: OTG for ID events in host mode
    - description: USB device mode for VBUS events
