* Samsung 10G Ethernet driver (SXGBE)
Required properties:
- compatible: Should be "samsung,sxgbe-v2.0a"
- reg: Address and length of the register set for the device
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
- interrupts: Should contain the SXGBE interrupts
These interrupts are ordered by fixed and follows variable
trasmit DMA interrupts, receive DMA interrupts and lpi interrupt.
index 0 - this is fixed common interrupt of SXGBE and it is always
available.
index 1 to 25 - 8 variable trasmit interrupts, variable 16 receive interrupts
and 1 optional lpi interrupt.
- phy-mode: String, operation mode of the PHY interface.
Supported values are: "sgmii", "xgmii".
- samsung,pbl: Integer, Programmable Burst Length.
Supported values are 1, 2, 4, 8, 16, or 32.
- samsung,burst-map: Integer, Program the possible bursts supported by sxgbe
This is an integer and represents allowable DMA bursts when fixed burst.
Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled.
When fixed length is needed for burst mode, it can be set within allowable
range.
Optional properties:
- mac-address: 6 bytes, mac address
- max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather
than the maximum frame size.
Example:
aliases {
ethernet0 = <&sxgbe0>;
};
sxgbe0: ethernet@1a040000 {
compatible = "samsung,sxgbe-v2.0a";
reg = <0 0x1a040000 0 0x10000>;
interrupt-parent = <&gic>;
interrupts = <0 209 4>, <0 185 4>, <0 186 4>, <0 187 4>,
