* Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller
Required properties:
- compatible : Should be "smsc,lan<model>", "smsc,lan9115"
- reg : Address and length of the io space for SMSC LAN
- interrupts : Should contain SMSC LAN interrupt line
- interrupt-parent : Should be the phandle for the interrupt controller
that services interrupts for this device
- phy-mode : String, operation mode of the PHY interface.
Supported values are: "mii", "gmii", "sgmii", "tbi", "rmii",
"rgmii", "rgmii-id", "rgmii-rxid", "rgmii-txid", "rtbi", "smii".
Optional properties:
- reg-shift : Specify the quantity to shift the register offsets by
- reg-io-width : Specify the size (in bytes) of the IO accesses that
should be performed on the device. Valid value for SMSC LAN is
2 or 4. If it's omitted or invalid, the size would be 2.
- smsc,irq-active-high : Indicates the IRQ polarity is active-high
- smsc,irq-push-pull : Indicates the IRQ type is push-pull
- smsc,force-internal-phy : Forces SMSC LAN controller to use
internal PHY
- smsc,force-external-phy : Forces SMSC LAN controller to use
external PHY
- smsc,save-mac-address : Indicates that mac address needs to be saved
before resetting the controller
- local-mac-address : 6 bytes, mac address
