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

+      If present, enables or disables the FX Fiber Mode.
+       - disable  = FX Fiber Mode disabled
+       - 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.
