Marvell Prestera Switch Chip bindings
|

-------------------------------------
|
||||
|
||||
Required properties:
|
||||
- compatible: one of the following
|
||||
"marvell,prestera-98dx3236",
|
||||
"marvell,prestera-98dx3336",
|
||||
"marvell,prestera-98dx4251",
|
||||
- reg: address and length of the register set for the device.
|
||||
- interrupts: interrupt for the device
|
||||
|
||||
Optional properties:
|
||||
- dfx: phandle reference to the "DFX Server" node
|
||||
|
||||
Example:
|
||||
|
||||
switch {
