Merge branch 'smsc911x-acpi'
Jeremy Linton says:
====================
Enable smsc911x for use with ACPI
This set of patches enables the front Ethernet port on the
ARM Juno development platform when used with an ACPI enabled kernel.
These patches covert the of_property* calls in the driver to the
DT/ACPI agnostic device_property* calls, and add the arm hardware
id to the acpi_match_table.
To support the above changes I copied a couple routines from
of_net into the properties.c file, and modified them to
be ACPI/DT agnostic. I'm not 100% sure this is the correct location
for these functions. But I think they are required to avoid having
a dozen different implementations scattered across assorted Ethernet
adapters that are being enabled to use ACPI properties.
