42fa8f17e4 dt-bindings: pse: tps23881: Clarify channels property description
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.

82566eb4ea dt-bindings: net: pse-pd: ti,tps23881: Add interrupt description
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.

ec82fa2c87 dt-bindings: pse: tps23881: add reset-gpios
The TPS23881 has an active-low reset pin that can be connected to an
SoC.  Document this with the device-tree binding.

12f86b9af9 dt-bindings: net: pse-pd: ti,tps23881: Fix missing "additionalProperties" constraints
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.
