1* Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller 2 3Required 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 : See ethernet.txt file in the same directory 10 11Optional 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 24 25Examples: 26 27lan9220@f4000000 { 28 compatible = "smsc,lan9220", "smsc,lan9115"; 29 reg = <0xf4000000 0x2000000>; 30 phy-mode = "mii"; 31 interrupt-parent = <&gpio1>; 32 interrupts = <31>; 33 reg-io-width = <4>; 34 smsc,irq-push-pull; 35}; 36
