T1040 L2switch Device Tree Binding
Copyright (C) 2013 Freescale Semiconductor Inc.
CONTENTS
- Overview
- L2switch Node
- Port Node
=====================================================================
Overview
DESCRIPTION
T1040 integrates a Gigabit Ethernet switch core with eight 10/100/1000 Mbps
Ethernet ports and two 10/100/1000/2500 Mbps ports.
=====================================================================
L2switch Node
Description
This node specifies the address range of l2switch configuration registers
and interrupts. It also contains a set of child nodes defining the
Ethernet ports.
PROPERTIES
- compatible
Usage: required
Value type: <string>
Definition: Must include "vitesse-9953"
- reg
Usage: required
Value type: <prop-encoded-array>
Definition: Standard property which specifies the physical address and
length of the l2switch configuration registers.
- interrupts
Usage: required
Value type: <prop_encoded-array>
Definition: Standard property, specifies the interrupts generated by
this device.
The value of the interrupts property consists of one interrupt
specifier. The format of the specifier is defined by the binding
document describing the node's interrupt parent.
=====================================================================
Port Node
Description
This node specifies the status and connection type of each of the Ethernet
ports.
PROPERTIES
- compatible
Usage: required
Value type: <string>
Definition: Must include "vitesse-9953-port"
- port-index
Usage: required
Value type: <u32>
Definition: Specifies the port index. Values 0, 1 are used by the two
internal 10/100/1000/2500 Mbps ports, values 2-9 are used by the
eight external 10/100/1000 Mbps ports.
- phy-connection-type
Usage: required
Value type: <string>
Definition: Specifies the controller/PHY interface type.
- status
Usage: optional
Value type: <string>
Definition: Standard property.
Indicates the operational status of the port. "disabled" is used
to indicate that the port is not usable (for example because the
QSGMII link to the PHYs is not available with current RCW).
- fixed-link
Usage: optional
Value type: <prop_encoded-array>
Definition: Specifies link parameters in the absence of a PHY.
<a b c d e> where a is emulated phy id - must be unique to among
all specified fixed-links, b is duplex - 0 half, 1 full, c is
link speed - 10/100/1000/2500, d is pause - 0 no pause, 1 pause,
e is asym_pause - 0 no asym_pause, 1 asym_pause.
- phy-handle
Usage: optional
Value type: <phandle>
Definition: The phandle for the PHY connected to this l2switch port.
Note: All other standard properties (see the ePAPR) are allowed but are
optional.
