Subject: [PATCH net v5 0/4] net: phy: bcm54811: Fix the PHY initialization

PATCH 1 - Add MII-Lite PHY interface mode as defined by Broadcom for
   their two-wire PHYs. It can be used with most Ethernet controllers
   under certain limitations (no half-duplex link modes etc.).

PATCH 2 - Add MII-Lite PHY interface type

PATCH 3 - Activation of MII-Lite interface mode on Broadcom bcm5481x
   PHYs

PATCH 4 - Fix the BCM54811 PHY initialization so that it conforms
   to the datasheet regarding a reserved bit in the LRE Control
   register, which must be written to zero after every device reset.
   Also fix the LRE Status register reading, there is another bit to
   be ignored on bcm54811.

Changes in v2:
  - Applied reviewers' comments
  - Divided into more patches (separated common and Broadcom
   PHY specific code)

Changes in v3:
  - Added MII-Lite documentation

Changes in v4:
  - Added missing Fixes headers

Changes in v5:
  - Removed unused PHY register bits definition
