Ethernet controllers may be connected to DPLL (Digital Phase Locked Loop)
pins for frequency synchronization purposes, such as in Synchronous
Ethernet (SyncE) configurations.

Add 'dpll-pins' and 'dpll-pin-names' properties to the generic
ethernet-controller schema. This allows describing the physical
connections between the Ethernet controller and the DPLL subsystem pins
in the Device Tree, enabling drivers to request and manage these
resources.

Please include a .dts patch in the series which actually makes use of
these new properties.

Actually, first you need a device (i.e. a specific ethernet 
controller bindings) using this and defining the number of dpll-pins 
entries and the names.
