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
