====================
ARM: Berlin: Ethernet support

This series introduce support for the Ethernet controller on Berlin SoCs,
using the existing pxa168 Ethernet driver. In order to do this, DT
support is added to the driver alongside some other modifications and
fixes.

This has been tested on a Berlin BG2Q DMP board.

Changes since v5:
	- fixed the build when building the driver as a module

Changes since v4:
        - removed the phy-addr property and added a phy subnode
        - added COMPILE_TEST for the pxa168_eth driver

Changes since v3:
        - moved the addition of pxa168_eth_get_mac_address() to the patch
          using it first

Changes since v2:
        - reworked how the MAC address is configured
        - made the clock anonymous

Changes since v1:
        - removed custom Berlin Ethernet driver
        - used the pxa168 Ethernet driver instead
        - made modifications to the pxa168 driver (DT support, fixes)
