Subject: [PATCH net 0/2] Add DT property to disable hibernation mode

From: Wei Fang <wei.fang@....com>

The patches add the ability to disable the hibernation mode of AR803x
PHYs. Hibernation mode defaults to enabled after hardware reset on
these PHYs. If the AR803x PHYs enter hibernation mode, they will not
provide any clock. For some MACs, they might need the clocks which
provided by the PHYs to support their own hardware logic.
So, the patches add the supoort to disable hibernation mode by adding
a boolean:
	qca,disable-hibernation
If one wished to disable hibernation mode to better match with the
specifical MAC, just add this property in the phy node of DT.
