1 | * Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller |
| 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 | |
| e8f08ee0 | 9 | - phy-mode : See ethernet.txt file in the same directory |
| 79f88ee9 SG |
10 | |
| 11 | Optional properties: | |
| 12 | - reg-shift : Specify the quantity to shift the register offsets by | |
| 13 | - reg-io-width : Specify the size (in bytes) of the IO accesses that | |
| 14 | should be performed on the device. Valid value for SMSC LAN is | |
| 15 | 2 or 4. If it's omitted or invalid, the size would be 2. | |
| 16 | - smsc,irq-active-high : Indicates the IRQ polarity is active-high | |
| 17 | - smsc,irq-push-pull : Indicates the IRQ type is push-pull | |
| 18 | - smsc,force-internal-phy : Forces SMSC LAN controller to use | |
| 19 | internal PHY | |
| 20 | - smsc,force-external-phy : Forces SMSC LAN controller to use | |
| 21 | external PHY | |
| 22 | - smsc,save-mac-address : Indicates that mac address needs to be saved | |
| 23 | before resetting the controller | |
