The stmmac driver use lots of pr_xxx functions to print information. This is bad since we cannot know which device logs the information. (moreover if two stmmac device are present) Furthermore, it seems that it assumes wrongly that all logs will always be subsequent by using a dev_xxx then some indented pr_xxx like this: kernel: sun7i-dwmac 1c50000.ethernet: no reset control found kernel: Ring mode enabled kernel: No HW DMA feature register supported kernel: Normal descriptors kernel: TX Checksum insertion supported So this patch replace all pr_xxx by their netdev_xxx counterpart. Excepts for some printing where netdev "cause" unpretty output like: sun7i-dwmac 1c50000.ethernet (unnamed net_device) (uninitialized): no reset control found In those case, I keep dev_xxx. In the same time I remove some "stmmac:" print since this will be a duplicate with that dev_xxx displays.

Initially the phy_bus_name was added to manipulate the driver name but it was recently just used to manage the fixed-link and then to take some decision at run-time. So the patch uses the is_pseudo_fixed_link and removes the phy_bus_name variable not necessary anymore. The driver can manage the mdio registration by using phy-handle, dwmac-mdio and own parameter e.g. snps,phy-addr. This patch takes care about all these possible configurations and fixes the mdio registration in case of there is a real transceiver or a switch (that needs to be managed by using fixed-link).

Originally, most of the platforms using this driver did not define an mdio subnode in the devicetree. Commit e34d65 ("stmmac: create of compatible mdio bus for stmmac driver") introduced a backward compatibily issue by using of_mdiobus_register explicitly with an mdio subnode. This patch fixes the issue by calling the function mdiobus_register, when mdio subnode is not found. The driver is now compatible with both modes.

This patch removes bus_id from mdio platform data, The reason to remove bus_id is, stmmac mdio bus_id is always same as stmmac bus-id, so there is no point in passing this in different variable.

This patch adds a basic check in stmmac_mdio_unregister to see if mdio bus registeration for this driver was actually sucessfull or not. Use case here is, if BSP considers using mdio-gpio bus along with stmmac driver by passing mdio_bus_data as NULL in platform data. Call to stmmac_mdio_register with mdio_bus_data as NULL returns 0, which is a considered sucessfull call form stmmac. Then again when we unload the driver we just call stmmac_mdio_unregister, this is were the actual problem is stmmac-mdio code dont really know at this instance of calling that stmmac_mdio_register was actually successful. So Adding a check in stmmac_mdio_unregister is always safe. Without this patch stmmac driver calls stmmac_mdio_register from stmmac_release which Segfaults as mii bus was never registered at the first point. Originally the this bug was found when unloading an stmmac driver instance which uses mdio-gpio for smi access.

Prior to this change, most PHY configuration parameters were passed into the STMMAC device as a separate PHY device. As well as being unusual, this made it difficult to make changes to the MAC/PHY relationship. This patch moves all the PHY parameters into the MAC configuration structure, mainly as a separate structure. This allows us to completely ignore the MDIO bus attached to a stmmac if desired, and not create the PHY bus. It also allows the stmmac driver to use a different PHY from the one it is connected to, for example a fixed PHY or bit banging PHY. Also derive the stmmac/PHY connection type (MII/RMII etc) from the mode can be passed into <platf>_configure_ethernet. STLinux kernel at git://git.stlinux.com/stm/linux-sh4-2.6.32.y.git provides several examples how to use this new infrastructure (that actually is easier to maintain and clearer).

This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file.
