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 : one or two interrupt specifiers 7 - The first interrupt is the SMSC LAN interrupt line 8 - The second interrupt (if present) is the PME (power 9 management event) interrupt that is able to wake up the host 10 system with a 50ms pulse on network activity 11- phy-mode : See ethernet.txt file in the same directory 12 13Optional 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- reset-gpios : a GPIO line connected to the RESET (active low) signal 27 of the device. On many systems this is wired high so the device goes 28 out of reset at power-on, but if it is under program control, this 29 optional GPIO can wake up in response to it. 30- vdd33a-supply, vddvario-supply : 3.3V analog and IO logic power supplies 31 32Examples: 33 34lan9220@f4000000 { 35 compatible = "smsc,lan9220", "smsc,lan9115"; 36 reg = <0xf4000000 0x2000000>; 37 phy-mode = "mii"; 38 interrupt-parent = <&gpio1>; 39 interrupts = <31>, <32>; 40 reset-gpios = <&gpio1 30 GPIO_ACTIVE_LOW>; 41 reg-io-width = <4>; 42 smsc,irq-push-pull; 43}; 44
