Merge branch 'netcp-next' 



Murali Karicheri says:

====================
NetCP: Add support for version 1.5

NetCP 1.5 is used in newer K2 SoCs from Texas Instruments
such as K2E, K2L etc. This patch series add support for Ethss
driver for this version of NetCP. While at it, fix couple of
bugs in the original driver.

One of the earlier patch "net: netcp: select davinci_mdio driver
by default" is folded onto this series.

Please review and let me know your comments.
