[POWERPC] Document phy-connection-type property
Since ucc_geth is being migrated to use the phylib, the existing (undocumented) 'interface' property is being deprecated in favour of 'phy-connection-type'. phy-connection-type is now maintained one-to-one with definitions in include/linux/phy.h, albeit in the form of a string. If not specified, "mii" is assumed. Signed-off-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
