Slave Properties:
Required properties:
-- phy_id : Specifies slave phy id
- phy-mode : See ethernet.txt file in the same directory
Optional properties:
- dual_emac_res_vlan : Specifies VID to be used to segregate the ports
- mac-address : See ethernet.txt file in the same directory
+- phy_id : Specifies slave phy id
- phy-handle : See ethernet.txt file in the same directory
Slave sub-nodes:
- fixed-link : See fixed-link.txt file in the same directory
- Either the properties phy_id and phy-mode,
- or the sub-node fixed-link can be specified
+ Either the property phy_id, or the sub-node
+ fixed-link can be specified
Note: "ti,hwmods" field is used to fetch the base address and irq
resources from TI, omap hwmod data base during device registration.
