From e4ccdfb78a47132f2d215658aab8902fc457c4b4 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Fri, 18 Aug 2023 04:07:46 +0100 Subject: [PATCH 082/125] net: pcs: lynxi: implement pcs_disable op When switching from 10GBase-R/5GBase-R/USXGMII to one of the interface modes provided by mtk-pcs-lynxi we need to make sure to always perform a full configuration of the PHYA. Implement pcs_disable op which resets the stored interface mode to PHY_INTERFACE_MODE_NA to trigger a full reconfiguration once the LynxI PCS driver had previously been deselected in favor of another PCS driver such as the to-be-added driver for the USXGMII PCS found in MT7988.
