1 * Samsung 10G Ethernet driver (SXGBE)
2
3 Required properties:
4 - compatible: Should be "samsung,sxgbe-v2.0a"
5 - reg: Address and length of the register set for the device
6 - interrupts: Should contain the SXGBE interrupts
7 These interrupts are ordered by fixed and follows variable
8 transmit DMA interrupts, receive DMA interrupts and lpi interrupt.
9 index 0 - this is fixed common interrupt of SXGBE and it is always
10 available.
11 index 1 to 25 - 8 variable transmit interrupts, variable 16 receive interrupts
12 and 1 optional lpi interrupt.
13 - phy-mode: String, operation mode of the PHY interface.
14 Supported values are: "sgmii", "xgmii".
15 - samsung,pbl: Integer, Programmable Burst Length.
16 Supported values are 1, 2, 4, 8, 16, or 32.
17 - samsung,burst-map: Integer, Program the possible bursts supported by sxgbe
18 This is an integer and represents allowable DMA bursts when fixed burst.
19 Allowable range is 0x01-0x3F. When this field is set fixed burst is enabled.
20 When fixed length is needed for burst mode, it can be set within allowable
21 range.
22
23 Optional properties:
24 - max-frame-size: Maximum Transfer Unit (IEEE defined MTU), rather
25 than the maximum frame size.
26
27 The MAC address will be determined using the optional properties
28 defined in ethernet.txt.
