* 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 interger 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.
|
||
|
|
|
||
|
|
