[PATCH v2] of: make of_get_phy_mode parse 'phy-connection-type'

From: Florian Fainelli
Date: Fri Nov 15 2013 - 01:24:12 EST


Per the ePAPR v1.1 specification, 'phy-connection-type' is the canonical
property name for describing an Ethernet to PHY connection type. Make
sure that of_get_phy_mode() also attempts to parse that property and
update the comments mentioning 'phy-mode' to also include
'phy-connection-type'.

Changes since v2:
- reworked the error condition to look nicer per Grant's suggestion
- added Grant's Acked-by tag
- fixed a typo in the commit message on "mentioning"
