Subject: [PATCH net-next 1/2] dt-bindings: dpll: Add clock ID property

Add property to specify the ID of the clock that the DPLL device
drives. The ID value represents Unique Clock Identified (EUI-64)
defined by IEEE 1588 standard.

The property is not mandatory because some DPLL devices can have
an ability to read this from HW. The situation is very similar
to network controllers without assigned MAC address.
