[PATCH v3 net-next 0/2] net: phy: add LAN8742 phy support

[Yuiko Oshino]

add LAN8742 phy support
update LAN88xx phy ID and phy ID mask so that it can coexist with LAN8742

The current phy IDs on the available hardware.
    LAN8742 0x0007C130, 0x0007C131
    LAN88xx 0x0007C132

v2->v3:
-added comments about the 0xfffffff2 mask that is for the differentiation and 
 the future revisions.

v1->v2:
-removed "REVIEW REQUEST3" from the PATCH 1/2.

Yuiko Oshino (2):
  net: phy: microchip: update LAN88xx phy ID and phy ID mask.
  net: phy: smsc: add LAN8742 phy support.

[PATCH v3 net-next 1/2] net: phy: microchip: update LAN88xx phy ID and phy ID mask.

[Yuiko Oshino]

update LAN88xx phy ID and phy ID mask because the existing code conflicts with the LAN8742 phy.

The current phy IDs on the available hardware.
        LAN8742 0x0007C130, 0x0007C131
        LAN88xx 0x0007C132
