1 * Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller
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
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
22 - smsc,force-external-phy : Forces SMSC LAN controller to use
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
