* AMD 10GbE driver (amd-xgbe)
|
|
|
|
Required properties:
|
|
- compatible: Should be "amd,xgbe-seattle-v1a"
|
|
- reg: Address and length of the register sets for the device
|
|
- MAC registers
|
|
- PCS registers
|
|
- interrupt-parent: Should be the phandle for the interrupt controller
|
|
that services interrupts for this device
|
|
- interrupts: Should contain the amd-xgbe interrupt
|
|
- clocks:
|
|
- DMA clock for the amd-xgbe device (used for calculating the
|
|
correct Rx interrupt watchdog timer value on a DMA channel
|
|
for coalescing)
|
|
- PTP clock for the amd-xgbe device
|
|
- clock-names: Should be the names of the clocks
|
|
- "dma_clk" for the DMA clock
|
|
- "ptp_clk" for the PTP clock
|
|
- phy-handle: See ethernet.txt file in the same directory
|
|
- phy-mode: See ethernet.txt file in the same directory
|
|
|
|
Optional properties:
|
|
- mac-address: mac address to be assigned to the device. Can be overridden
|
|
by UEFI.
|
|
- dma-coherent: Present if dma operations are coherent
|
|
|
|
Example:
|
|
xgbe@e0700000 {
|
|
compatible = "amd,xgbe-seattle-v1a";
|
|
reg = <0 0xe0700000 0 0x80000>,
|
|
<0 0xe0780000 0 0x80000>;
|
|
interrupt-parent = <&gic>;
|
|
interrupts = <0 325 4>;
|
|
clocks = <&xgbe_dma_clk>, <&xgbe_ptp_clk>;
|
|
clock-names = "dma_clk", "ptp_clk";
|
|
phy-handle = <&phy>;
|
|
phy-mode = "xgmii";
|
|
mac-address = [ 02 a1 a2 a3 a4 a5 ];
|
|
};
