This patch serie adds support for Microchip lan966x serdes. The lan966x
device which contains this serdes has 8 interfaces, consisting of 2
copper transceivers, 3 Serdes and 2 RGMII interfaces and 2 of the
Serdes support QSGMII.

The following table shows which interfaces can be supported by the port.

PortNumber    Max Speed    Ethernet interface options
    0            1Gbps       CuPHY, 1G SGMII or QSGMII
    1            1Gbps       CuPHY, 1G SGMII or QSGMII
    2          2.5Gbps       2.5G SGMII, QSGMII, RGMII
    3          2.5Gbps       2.5G SGMII, QSGMII, RGMII
    4          2.5Gbps       2.5G SGMII, QSGMII
    5            1Gbps       QSGMII, RGMII
    6            1Gbps       QSGMII, RGMII
    7            1Gbps       QSGMII

v1 -> v2:
- replace the regmap with iomem
- update DT bindings

  dt-bindings: phy: Add lan966x-serdes binding
  dt-bindings: phy: Add binding includes for lan966x serdes
  phy: Add lan966x ethernet serdes PHY driver
