[PATCH v3 0/2] usb: typec: ucsi_ccg: Add CYPD6129/CYPD6229 support

[Akash Kumar]

This series adds Device Tree and driver support for the Cypress CYPD6129
and CYPD6229 dual Type-C PD controllers.

The controllers use the existing I2C-based UCSI CCG interface. The series
updates the binding to describe the new compatibles and controller-specific
properties, and extends the UCSI CCG OF match table accordingly.

Patch 1 updates the Device Tree binding to:
- Add CYPD6129 and CYPD6229 compatible strings.
- Support the CYPD6229 fallback-compatible relationship with CYPD6129.
- Allow controller-specific I2C addresses and interrupt configurations.
- Add pinctrl and wakeup-source properties.
- Preserve the existing CYPD4226-specific constraints.

Patch 2 adds CYPD6129 and CYPD6229 to the UCSI CCG OF device ID table.

Changes in v3:
- Fold the new controller descriptions into the existing
  cypress,cypd4226.yaml binding.
- Drop the standalone cypress,cypd6129.yaml binding file.
- Drop the Shikra DTS changes from this series.
- Add conditional binding constraints for CYPD4226 and CYPD6129/CYPD6229.
- Address review comments from the v1 submission.

[PATCH v3 1/2] dt-bindings: usb: cypress,cypd4226: Add cypd6129/cypd6229 support

[Akash Kumar]

From: Akash Kumar <akakum@qti.qualcomm.com>

Extend the binding to cover the Cypress cypd6129 and cypd6229 dual
Type-C PD controllers, which share the same I2C-controlled interface
as the cypd4226. Also add pinctrl and wakeup-source properties, and
relax reg/interrupts constraints that only applied to cypd4226.
