[PATCH net-next v2 0/3] Preserve PSE PD692x0 configuration across reboots

Posted by Kory Maincent 2 months ago

From: Kory Maincent (Dent Project) <kory.maincent@bootlin.com>

Previously, the driver would always reconfigure the PSE hardware on
probe, causing a port matrix reflash that resulted in temporary power
loss to all connected devices. This change maintains power continuity
by preserving existing configuration when the PSE has been previously
initialized.
