dt-bindings: pse-pd: ti,tps23881: Add TPS23881B

2025-11-01T00:56:32Z

Add the TPS23881B I2C power sourcing equipment controller to the list of supported devices. Falling back to the TPS23881 predecessor device is not suitable as firmware loading needs to handled differently by the driver. The TPS23881 and TPS23881B devices require different firmware. Trying to load the TPS23881 firmware on a TPS23881B device fails and must therefore be omitted.

dt-bindings: pse: tps23881: Clarify channels property description

2025-06-24T08:57:43Z

Improve the channels property description to better explain the relationship between physical delivery channels and PSE PI pairsets. The previous description was unclear about how channels are referenced and used in the port matrix mapping.

dt-bindings: net: pse-pd: ti,tps23881: Add interrupt description

2025-06-19T02:00:19Z

Add an interrupt property to the device tree bindings for the TI TPS23881 PSE controller. The interrupt is primarily used to detect classification and disconnection events, which are essential for managing the PSE controller in compliance with the PoE standard. Interrupt support is essential for the proper functioning of the TPS23881 controller. Without it, after a power-on (PWON), the controller will no longer perform detection and classification. This could lead to potential hazards, such as connecting a non-PoE device after a PoE device, which might result in magic smoke.

dt-bindings: net: pse-pd: microchip,pd692x0: Add manager regulator supply

2025-06-19T02:00:18Z

Adds the regulator supply parameter of the managers. Update also the example as the regulator supply of the PSE PIs should be the managers itself and not an external regulator.

dt-bindings: net: pse-pd: ti,tps23881: Fix missing "additionalProperties" constraints

2024-05-27T23:49:16Z

The child nodes are missing "additionalProperties" constraints which means any undocumented properties or child nodes are allowed. Add the constraints and all the undocumented properties exposed by the fix.
