This patch is an attempt to gather the Ethernet related bindings in one file, like it's done in the MMC and some other subsystems. It should save some of the trouble of documenting several properties over and over in each binding document, instead only making reference to the main file. I have used the Embedded Power Architecture(TM) Platform Requirements (ePAPR) standard as a base for the properties description, also documenting some ad-hoc properties that have been introduced over time despite having direct analogs in ePAPR.

* Smart Mixed-Signal Connectivity (SMSC) LAN911x/912x Controller
|
|
|
|
Required properties:
|
|
- compatible : Should be "smsc,lan<model>", "smsc,lan9115"
|
|
- reg : Address and length of the io space for SMSC LAN
|
|
- interrupts : Should contain SMSC LAN interrupt line
|
|
- interrupt-parent : Should be the phandle for the interrupt controller
|
|
that services interrupts for this device
|
|
- 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
|
|
|
|
Examples:
|
|
|
|
lan9220@f4000000 {
|
|
compatible = "smsc,lan9220", "smsc,lan9115";
|
|
reg = <0xf4000000 0x2000000>;
|
|
phy-mode = "mii";
|
|
interrupt-parent = <&gpio1>;
|
|
interrupts = <31>;
|
|
reg-io-width = <4>;
|
|
smsc,irq-push-pull;
|
|
};
