Subject: [PATCH v4 0/3] net: phy: bcm5481x: add support for BroadR-Reach mode

PATCH 1 - Add the 10baseT1BRR_Full link mode

PATCH 2 - Add the definitions of LRE registers, necessary to use
   BroadR-Reach modes on the BCM5481x PHY

PATCH 3 - Implementation of the BroadR-Reach modes for the Broadcom
   PHYs

Changes in v2:
  - Divided into multiple patches, removed useless link modes

Changes in v3:
  - Fixed uninitialized variable in bcm5481x_config_delay_swap function

Changes in v4:
  - Improved the division of functions between bcm-phy library and broadcom.c
  - Changed the BroadR-Reach / IEEE mode switching to device tree boolean as
    these modes are mutually exclusive and barely could coexist in one hardware
  - Made the link mode selection compatible with current ethtool (i.e. the
    linkmode is selected by choosing speed and master-slave)

Kamil Horák - 2N (3):
  net: phy: bcm54811: New link mode for BroadR-Reach
  net: phy: bcm54811: Add LRE registers definitions
  net: phy: bcm-phy-lib: Implement BroadR-Reach link modes
