Subject: [PATCH net-next v4 0/2] net: phy: Support master-slave config via device tree
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 v4:
- add Reviewed-by
- rebase against latest net-next
changes v3:
- rename master-slave to timing-role
- add prefer-master/slave support

ethernet PHYs
net: phy: Add support for PHY timing-role configuration via device
tree
