Subject: [RFC PATCH 0/2] phy: core: better support for multi-phy in phy-core

In multi-phy PHY providers, each PHY should be modeled as sub-node of PHY
provider. So it makes sense for the controller node to have the phandle for
the sub-node instead of the PHY-provider node in the 'phy' property.

This patch series added support so that the controller node can have the
phandle to the sub-node. So if the phy specifier does not have any other
fields other than the phandle (and the PHY driver uses the default xlate),
phy_get will return the correct PHY.
However if the phy_sepcifier has other fields and the PHY driver provides
its own xlate, the PHY driver can use the *phy->dev.of_node*. (note that
now phy->dev.of_node will have the node pointer of the sub-node).

Kishon Vijay Abraham I (2):
  phy: core: Fix of_phy_provider_lookup to return PHY provider for sub
    node
  phy: core: the node pointer of PHY need not be the same as that of
    PHY provider
