* Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller Required properties: - compatible : Should be "smsc,lan", "smsc,lan9115" - reg : Address and length of the io space for SMSC LAN - interrupts : one or two interrupt specifiers - The first interrupt is the SMSC LAN interrupt line - The second interrupt (if present) is the PME (power management event) interrupt that is able to wake up the host system with a 50ms pulse on network activity - phy-mode : See ethernet.txt file in the same directory 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 - reset-gpios : a GPIO line connected to the RESET (active low) signal of the device. On many systems this is wired high so the device goes out of reset at power-on, but if it is under program control, this optional GPIO can wake up in response to it. - vdd33a-supply, vddvario-supply : 3.3V analog and IO logic power supplies Examples: lan9220@f4000000 { compatible = "smsc,lan9220", "smsc,lan9115"; reg = <0xf4000000 0x2000000>; phy-mode = "mii"; interrupt-parent = <&gpio1>; interrupts = <31>, <32>; reset-gpios = <&gpio1 30 GPIO_ACTIVE_LOW>; reg-io-width = <4>; smsc,irq-push-pull; };
