This patch series adds support for MT7531. MT7531 is the next generation of MT7530 which could be found on Mediatek router platforms such as MT7622 or MT7629. It is also a 7-ports switch with 5 giga embedded phys, 2 cpu ports, and the same MAC logic of MT7530. Cpu port 6 only supports SGMII interface. Cpu port 5 supports either RGMII or SGMII in different HW SKU, but cannot be muxed to PHY of port 0/4 like mt7530. Due to support for SGMII interface, pll, and pad setting are different from MT7530. MT7531 SGMII interface can be configured in following mode: - 'SGMII AN mode' with in-band negotiation capability which is compatible with PHY_INTERFACE_MODE_SGMII. - 'SGMII force mode' without in-band negotiation which is compatible with 10B/8B encoding of PHY_INTERFACE_MODE_1000BASEX with fixed full-duplex and fixed pause. - 2.5 times faster clocked 'SGMII force mode' without in-band negotiation which is compatible with 10B/8B encoding of PHY_INTERFACE_MODE_2500BASEX with fixed full-duplex and fixed pause. v2 -> v3 - Keep the same setup logic of mt7530/mt7621 because these series of patches is for adding mt7531 hardware. - Do not adjust rgmii delay when vendor phy driver presents in order to prevent double adjustment by suggestion of Andrew Lunn. - Remove redundant 'Example 4' from dt-bindings by suggestion of Rob Herring. - Fix typo. v1 -> v2 - change phylink_validate callback function to support full-duplex gigabit only to match hardware capability. - add description of SGMII interface. - configure mt7531 cpu port in fastest speed by default. - parse SGMII control word for in-band negotiation mode. - configure RGMII delay based on phy.rst. - Rename the definition in the header file to avoid potential conflicts. - Add wrapper function for mdio read/write to support both C22 and C45. - correct fixed-link speed of 2500base-x in dts. - add MT7531 port mirror setting.
