From: Ken Ma <m...@marvell.com>This patch adds a separate driver for the MDIO interface of the Marvell Ethernet controllers based on driver model. There are two reasons to have a separate driver rather than including it inside the MAC driver itself: *) The MDIO interface is shared by all Ethernet ports, so a driver must guarantee non-concurrent accesses to this MDIO interface. The most logical way is to have a separate driver that handles this single MDIO interface, used by all Ethernet ports. *) The MDIO interface is the same between the existing mv643xx_eth driver and the new mvneta/mvpp2 driver. Even though it is for now only used by the mvneta/mvpp2 driver, it will in the future be used by the mv643xx_eth driver as well. This driver supports SMI IEEE for 802.3 Clause 22 and XSMI for IEEE 802.3 Clause 45. This patch also adds device tree binding for marvell MDIO driver. Signed-off-by: Ken Ma <m...@marvell.com> Reviewed-by: Chris Packham <judge.pack...@gmail.com> --- Changes in v4: - Use wait_for_bit_le32() instead of implementing private busy wait polling function. Changes in v3: - Move marvell mdio driver to driver/net/mdio folder; - Update codes according to mdio uclass implementation updates. Changes in v2: - Fix error printing: - Change some debug to pr_err; - mii bus has no parent member and it is not a udevice, so dev_err is changed to pr_err for mii bus error printings.
