net: phy: Allow pre-declaration of MDIO devices Allow board support code to collect pre-declarations for MDIO devices by registering them with mdiobus_register_board_info(). SPI and I2C buses have a similar feature, we were missing this for MDIO devices, but this is particularly useful for e.g: MDIO-connected switches which need to provide their port layout (often board-specific) to a MDIO Ethernet switch driver.

net: phy: Allow building mdio-boardinfo into the kernel mdio-boardinfo contains code that is helpful for platforms to register specific MDIO bus devices independent of how CONFIG_MDIO_DEVICE or CONFIG_PHYLIB will be selected (modular or built-in). In order to make that possible, let's do the following: - descend into drivers/net/phy/ unconditionally - make mdiobus_setup_mdiodev_from_board_info() take a callback argument which allows us not to expose the internal MDIO board info list and mutex, yet maintain the logic within the same file - relocate the code that creates a MDIO device into drivers/net/phy/mdio_bus.c - build mdio-boardinfo.o into the kernel as soon as MDIO_DEVICE is defined (y or m) Fixes: 90eff9096c01 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Fixes: 648ea0134069 ("net: phy: Allow pre-declaration of MDIO devices") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Tested-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.
