* Socionext NetSec Ethernet Controller IP
Required properties:
- compatible: Should be "socionext,synquacer-netsec"
- reg: Address and length of the control register area, followed by the
address and length of the EEPROM holding the MAC address and
microengine firmware
- interrupts: Should contain ethernet controller interrupt
- clocks: phandle to the PHY reference clock
- clock-names: Should be "phy_ref_clk"
- phy-mode: See ethernet.txt file in the same directory
- phy-handle: See ethernet.txt in the same directory.
- mdio device tree subnode: When the Netsec has a phy connected to its local
mdio, there must be device tree subnode with the following
required properties:
- #address-cells: Must be <1>.
- #size-cells: Must be <0>.
For each phy on the mdio bus, there must be a node with the following
- compatible: Refer to phy.txt
- reg: phy id used to communicate to phy.
Optional properties: (See ethernet.txt file in the same directory)
- dma-coherent: Boolean property, must only be present if memory
accesses performed by the device are cache coherent.
- max-speed: See ethernet.txt in the same directory.
- max-frame-size: See ethernet.txt in the same directory.
The MAC address will be determined using the optional properties
defined in ethernet.txt.
