Subject: [PATCH net-next v3 0/2] net: stmmac: Fix PHY attach when custom PCS is in use
Date: Wed, 29 Jul 2026 15:42:35 +0800 [thread overview]
Message-ID: <20260729074237.2624940-1-zxyan0222@gmail.com> (raw)
This series fixes the issue where stmmac platforms using a custom PCS
via the pcs_init callback fail to probe when no phy-handle is specified
in the device tree.
Patch 1 skips the PHY attach in stmmac when a custom PCS is already
configured via priv->hw->phylink_pcs and phy_addr is invalid, avoiding
the "no phy found" error for platforms that manage link state entirely
through the PCS.
Patch 2 is Russell King's phylink patch that relaxes phylink_expects_phy()
to allow PHYs to be attached in 802.3z inband mode.
v3:
- Move the priv->hw->phylink_pcs check inside the "addr < 0" branch
to avoid skipping the phy_addr fallback for boards with both a PCS
and a PHY
- Reverse patch order: stmmac fix first, phylink change second
v2:
- Include Russell's phylink patch as prerequisite
- This is now a 2-patch series targeting net-next

net: phylink: allow PHYs to be attached in 802.3z inband mode
