* 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
|
|
|
|
Examples:
|
|
|
|
lan9220@f4000000 {
|
|
compatible = "smsc,lan9220", "smsc,lan9115";
|
|
reg = <0xf4000000 0x2000000>;
|
|
phy-mode = "mii";
|
|
interrupt-parent = <&gpio1>;
|
|
interrupts = <31>;
|
|
reg-io-width = <4>;
|
|
smsc,irq-push-pull;

};
