After commit171a9bae68("staging/octeon: Allow test build on !MIPS"), the following combination of configs cause a few Kconfig warnings and build errors (distilled from arm allyesconfig and Randy's randconfig builds): CONFIG_NETDEVICES=y CONFIG_STAGING=y CONFIG_COMPILE_TEST=y and CONFIG_OCTEON_ETHERNET as either a module or built-in. WARNING: unmet direct dependencies detected for MDIO_OCTEON Depends on [n]: NETDEVICES [=y] && MDIO_DEVICE [=y] && MDIO_BUS [=y] && 64BIT [=n] && HAS_IOMEM [=y] && OF_MDIO [=n] Selected by [y]: - OCTEON_ETHERNET [=y] && STAGING [=y] && (CAVIUM_OCTEON_SOC || COMPILE_TEST [=y]) && NETDEVICES [=y] In file included from ../drivers/net/phy/mdio-octeon.c:14: ../drivers/net/phy/mdio-cavium.h:111:36: error: implicit declaration of function ‘writeq’; did you mean ‘writel’? [-Werror=implicit-function-declaration] 111 | #define oct_mdio_writeq(val, addr) writeq(val, (void *)addr) | ^~~~~~ CONFIG_64BIT is not strictly necessary if the proper readq/writeq definitions are included from io-64-nonatomic-lo-hi.h. CONFIG_OF_MDIO is not needed when CONFIG_COMPILE_TEST is enabled because of commitf9dc9ac516("of/mdio: Add dummy functions in of_mdio.h.").
