In practice, phy-mode is typically used, and phy-connection-type is
not used much. All new user tend to be phy-mode.
~/linux$ grep -r phy-mode arch/* | wc
1561 6258 113122
~/linux$ grep -r phy-connection-type arch/* | wc
372 1489 28981
Most of the phy-connection-type appear in PowerPC.
~/linux$ grep -r phy-connection-type arch/powerpc/* | wc
247 990 18335
It was the early adopter of DT, long before ARM. The DT standard of
the time, which PowerPC followed, said to use
phy-connection-type. When ARM started using DT, it did not follow the
standard too well, and phy-mode got used a lot. Officially, phy-mode
is deprecated because it is not part of the standard. But practice
does not always follow the standard.
So both are O.K, all the generic code accepts both, and there is no
real reason to change.
