| 2 | |
| 3 | Required properties: |
| 4 | - compatible : Should be "smsc,lan<model>", "smsc,lan9115" |
| 5 | - reg : Address and length of the io space for SMSC LAN |
| 6 | - interrupts : Should contain SMSC LAN interrupt line |
| 7 | - interrupt-parent : Should be the phandle for the interrupt controller |
| 8 | that services interrupts for this device |
| 9 | - phy-mode : String, operation mode of the PHY interface. |
| 10 | Supported values are: "mii", "gmii", "sgmii", "tbi", "rmii", |
| 11 | "rgmii", "rgmii-id", "rgmii-rxid", "rgmii-txid", "rtbi", "smii". |
| 12 | |
| 13 | Optional properties: |
| 14 | - reg-shift : Specify the quantity to shift the register offsets by |
| 15 | - reg-io-width : Specify the size (in bytes) of the IO accesses that |
| 16 | should be performed on the device. Valid value for SMSC LAN is |
| 17 | 2 or 4. If it's omitted or invalid, the size would be 2. |
| 18 | - smsc,irq-active-high : Indicates the IRQ polarity is active-high |
| 19 | - smsc,irq-push-pull : Indicates the IRQ type is push-pull |
| 20 | - smsc,force-internal-phy : Forces SMSC LAN controller to use |
| 21 | internal PHY |
| 22 | - smsc,force-external-phy : Forces SMSC LAN controller to use |
| 23 | external PHY |
| 24 | - smsc,save-mac-address : Indicates that mac address needs to be saved |
| 25 | before resetting the controller |
| 26 | - local-mac-address : 6 bytes, mac address |
| 27 | |
| 28 | Examples: |
| 29 | |
| 30 | lan9220@f4000000 { |
| 31 | compatible = "smsc,lan9220", "smsc,lan9115"; |
| 32 | reg = <0xf4000000 0x2000000>; |
| 33 | phy-mode = "mii"; |
| 34 | interrupt-parent = <&gpio1>; |
| 35 | interrupts = <31>; |
| 36 | reg-io-width = <4>; |
| 37 | smsc,irq-push-pull; |
| 38 | }; |
