[PATCH net-next v2 0/7] net-next: dsa: mt7530: add support for MT7531

[Landen Chao]

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. 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-bnad 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-bnad negotiation
    which is compatible with 10B/8B encoding of
    PHY_INTERFACE_MODE_2500BASEX with fixed full-duplex and fixed pause.

changes between 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.
