[PATCH net-next 1/2] dt-bindings: net: sff,sfp: Describe power supply pins

From: Romain Gantois

Date: Tue Mar 03 2026 - 09:13:16 EST


SFP cages and soldered-on SFF transceivers have two separate power supply
pins: one for the transmitter circuit, and one for the receiver circuit.

Describe these two pins and the regulators supplying them.
