From 12589892f41c4c645c80ef9f036f7451a6045624 Mon Sep 17 00:00:00 2001 From: Cai Xinchen Date: Thu, 12 Mar 2026 06:59:06 +0000 Subject: [PATCH] dpaa2: add independent dependencies for FSL_DPAA2_SWITCH Since the commit 84cba72956fd ("dpaa2-switch: integrate the MAC endpoint support") included dpaa2-mac.o in the driver, but it didn't select PCS_LYNX, PHYLINK and FSL_XGMAC_MDIO. it will lead to link error, such as undefined reference to `phylink_ethtool_ksettings_set' undefined reference to `lynx_pcs_create_fwnode' And the same reason as the commit d2624e70a2f53 ("dpaa2-eth: select XGMAC_MDIO for MDIO bus support"), enable the FSL_XGMAC_MDIO Kconfig option in order to have MDIO access to internal and external PHYs. Because dpaa2-switch uses fsl_mc_driver APIs, add depends on FSL_MC_BUS && FSL_MC_DPIO as FSL_DPAA2_SWITCH do. FSL_XGMAC_MDIO and FSL_MC_BUS depend on OF, thus the dependence of FSL_MC_BUS can satisfy FSL_XGMAC_MDIO's OF requirement.
