Subject: [PATCH net-next 0/3] Preserve PSE PD692x0 configuration across reboots
Date: Tue, 30 Sep 2025 11:12:59 +0200 [thread overview]
Message-ID: <20250930-feature_pd692x0_reboot_keep_conf-v1-0-620dce7ee8a2@bootlin.com> (raw)
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.
