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
