Ah, very nice! This way it will actually work to replace a number
of older drivers that require a specific clock name.
I'm glad you like it.
I still think we should change the phy subsystem to allow the
same, that would make it more consistent here, and avoid the
need for coming up with a number of bogus phy names for random
drivers that can only ever have one phy.
I'm not disagreeing, but that will have to be a battle for
another day. Currently the dt-bindings for phy actually
make phy-names mandatory at the bindings-description level, so
someone would first need to change the specification.
Documentation/devicetree/bindings/phy/phy-bindings.txt:
"""
PHY user node
=============
Required Properties:
phys : the phandle for the PHY device (used by the PHY subsystem)
phy-names : the names of the PHY corresponding to the PHYs present in the
*phys* phandle
"""

Hans
