Subject: [PATCH v2 0/9] dt-bindings: Convert TWL4030/6040 family binding to DT schema

Hi,

This series modernizes the Device Tree bindings for the Texas
Instruments TWL4030/TWL6040 family by converting all remaining
legacy TXT bindings to the structured YAML DT schema format.

This improves the bindings by adding formal type checking, clear property
definitions, and machine-readable examples, which allows for automated
validation and better documentation for developers.

This v2 series addresses feedback from the initial submission, adds a new
patch to fix validation errors that were uncovered by the stricter schemas,
and includes several other minor improvements.

Thank you,
Jihed

Changes from v2:

  - Add new patch (9/9) to fix the parent ti,twl.yaml binding by adding
    the missing sub-node definitions, resolving dtbs_check errors.
  - (1/9) ti,twl4030-audio: Moved binding to sound/, added enum for
    ti,enable-vibra, and simplified the example.
  - (2/9) ti,twl6040: Renamed twl6040,audpwron-gpio to ti,audpwron-gpio
    to fix a vendor prefix validation error.
  - (8/9) ti,twlxxxx-usb: Added '#phy-cells' property to support the
    standard PHY framework.
  - (7/9) omap-twl4030: Minor cosmetic fixes, retaining Acked-by Mark Brown.
  - Other patches: Minor description and formatting cleanups.

The following nine patches are included in this series:
