This patch series adds support for configuring the master/slave role of
PHYs via the device tree. A new `master-slave` property is introduced in
the device tree bindings, allowing PHYs to be forced into either master
or slave mode. This is particularly necessary for Single Pair Ethernet
(SPE) PHYs (1000/100/10Base-T1), where hardware strap pins may not be
available or correctly configured, but it is applicable to all PHY
types.

changes v5:
- sync DT options with ethtool nameing.

changes v4:
- add Reviewed-by
- rebase against latest net-next

changes v3:
- rename  master-slave to timing-role
- add prefer-master/slave support

Oleksij Rempel (2):
  dt-bindings: net: ethernet-phy: Add timing-role role property for
    ethernet PHYs
  net: phy: Add support for PHY timing-role configuration via device
    tree
