The PHY muxing feature makes use of this. - -This is problematic as the PHY may be attached before the switch is -initialised, in which case, the PHY will fail to be attached. - -Since commit 91374ba537bd ("net: dsa: mt7530: support OF-based registration -of switch MDIO bus"), we can describe the switch PHYs on the MDIO bus of -the switch on the device tree. Extend the check to detect PHY muxing when -the PHY is defined on the MDIO bus of the switch on the device tree. - -When the PHY is described this way, the switch will be initialised first, -then the switch MDIO bus will be registered. Only after these steps, the -PHY will be attached. - -Signed-off-by: Arınç ÜNAL <arinc.unal@arinc9.com> ---- -Changes in v2: -- Address the terminology on the patch log. -- Link to v1: https://lore.kernel.org/r/20240429-b4-for-netnext-mt7530-use-switch-mdio-bus-for-phy-muxing-v1-1-1f775983e155@arinc9.com ---- - drivers/net/dsa/mt7530.c | 3 ++- - 1 file changed, 2 insertions(+), 1 deletion(-) - - ---- -base-commit: 5c4c0edca68a5841a8d53ccd49596fe199c8334c -change-id: 20240429-b4-for-netnext-mt7530-use-switch-mdio-bus-for-phy-muxing-586269371c55 - -Best regards, - ---- a/drivers/net/dsa/mt7530.c -+++ b/drivers/net/dsa/mt7530.c -@@ -2488,7 +2488,8 @@ mt7530_setup(struct dsa_switch *ds) - if (!phy_node) - continue; - -- if (phy_node->parent == priv->dev->of_node->parent) { -+ if (phy_node->parent == priv->dev->of_node->parent || -+ phy_node->parent->parent == priv->dev->of_node) { - ret = of_get_phy_mode(mac_np, &interface); - if (ret && ret != -ENODEV) { - of_node_put(mac_np); |
