Commit a243ecc323b9 ("net: mdio: xgene: Use device_get_match_data()")
dropped the unconditional use of xgene_mdio_of_match resulting in this
warning:

drivers/net/mdio/mdio-xgene.c:303:34: warning: unused variable 'xgene_mdio_of_match' [-Wunused-const-variable]

The fix is to drop of_match_ptr() which is not necessary because DT is
always used for this driver (well, it could in theory support ACPI only,
but CONFIG_OF is always enabled for arm64).

net: mdio-mux: fix C45 access returning -EIO after API change 2023-10-19T01:08:23+00:00 Vladimir Oltean vladimir.oltean@nxp.com 2023-10-17T14:31:44+00:00 1f9f2143f24e224a8582a5d54918c43b9121eccc The mii_bus API conversion to read_c45() and write_c45() did not cover the mdio-mux driver before read() and write() were made C22-only. This broke arch/arm64/boot/dts/freescale/fsl-ls1028a-qds-13bb.dtso. The -EOPNOTSUPP from mdiobus_c45_read() is transformed by get_phy_c45_devs_in_pkg() into -EIO, is further propagated to of_mdiobus_register() and this makes the mdio-mux driver fail to probe the entire child buses, not just the PHYs that cause access errors. Fix the regression by introducing special c45 read and write accessors to mdio-mux which forward the operation to the parent MDIO bus.
