net: pcs-xpcs: depend on MDIO_BUS instead of selecting it The below compile time error can be seen when PHYLIB is configured as a module. ld: drivers/net/pcs/pcs-xpcs.o: in function `xpcs_read': pcs-xpcs.c:(.text+0x29): undefined reference to `mdiobus_read' ld: drivers/net/pcs/pcs-xpcs.o: in function `xpcs_soft_reset.constprop.7': pcs-xpcs.c:(.text+0x80): undefined reference to `mdiobus_write' ld: drivers/net/pcs/pcs-xpcs.o: in function `xpcs_config_aneg': pcs-xpcs.c:(.text+0x318): undefined reference to `mdiobus_write' ld: pcs-xpcs.c:(.text+0x38e): undefined reference to `mdiobus_write' ld: pcs-xpcs.c:(.text+0x3eb): undefined reference to `mdiobus_write' ld: pcs-xpcs.c:(.text+0x437): undefined reference to `mdiobus_write' ld: drivers/net/pcs/pcs-xpcs.o:pcs-xpcs.c:(.text+0xb1e): more undefined references to `mdiobus_write' follow PHYLIB being a module leads to MDIO_BUS being a module as well while the XPCS is still built-in. What should happen in this configuration is that PCS_XPCS should be forced to build as module. However, that select only acts in the opposite way so we should turn it into a depends. Fix this up by explicitly depending on MDIO_BUS.

controllers.
net: phy: add Lynx PCS module Add a Lynx PCS module which exposes the necessary operations to drive the PCS using phylink. The majority of the code is extracted from the Felix DSA driver, which will be also modified in a later patch, and exposed as a separate module for code reusability purposes. As such, this aims at feature and bug parity with the existing Felix DSA driver, and thus USXGMII, SGMII, QSGMII and 2500Base-X (only w/o in-band AN) are supported by the Lynx PCS module since these were also supported by Felix. The module can only be enabled by the drivers in need and not user selectable. Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
