Subject: [PATCH net-next 1/2] dt-bindings: net: sff,sfp: Describe power supply pins
Date: Tue, 03 Mar 2026 14:54:26 +0100 [thread overview]
Message-ID: <20260303-sfp-regulators-v1-1-7101ae34cb84@bootlin.com> (raw)
In-Reply-To: <20260303-sfp-regulators-v1-0-7101ae34cb84@bootlin.com>
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.
