The updated pattern allows for additional node names, including those with a hyphen followed by a hexadecimal digit. Before this change, the pattern ^ethernet-pse(@.*)?$ only allowed for node names like "ethernet-pse" or "ethernet-pse@1". With the new pattern node names like "ethernet-pse-1" are now also valid.

The addition of these nodes enables support for PoDL in PRTT1C devices, allowing power delivery and data transmission over a single twisted pair. The new PoDL PSE regulator nodes provide voltage capability information of the current board design, which can be used as a hint for system administrators when configuring and managing power settings. This update enhances the versatility and simplifies the power management of PRTT1C devices while ensuring compatibility with connected Powered Devices (PDs). After applying this patch, the power delivery can be controlled from user space with a patched [1] ethtool version using the following commands: ethtool --set-pse t1l2 podl-pse-admin-control enable to enable power delivery, and ethtool --show-pse t1l2 to display the PoDL PSE settings. By integrating PoDL PSE support into the PRTT1C devicetree, users can benefit from streamlined power and data connections in their deployments, improving overall system efficiency and reducing cabling complexity.
