Subject: [PATCH v2 1/6] dt-bindings: net: Add bindings for PHY DP83640
The DP83640 is a PTP PHY. Some of his features can be enabled by
hardware straps. There is not binding yet.
Add a device tree binding to be able to override the hardware strap
configuration when needed.

+description: |
+ The DP83640 Precision PHYTER device is an Ethernet PHY providing PTP
+ capabilities based on IEEE 1588 standard.
+
+ This device interfaces directly to the MAC layer through the
+ IEEE 802.3 Standard Media Independent Interface (MII), or Reduced MII (RMII).
+
+ Specifications about the Ethernet PHY can be found at:
+ https://www.ti.com/lit/gpn/dp83640

+ - enable = FX Fiber Mode enabled
+ Fiber mode enabling can also be strapped. If the strap pin is not set
+ correctly or not set at all then this can be used to configure it.
