1 * Synopsys DWC Ethernet QoS IP version 4.10 driver (GMAC)
5 - compatible: Should be "snps,dwc-qos-ethernet-4.10"
6 - reg: Address and length of the register set for the device
7 - clocks: Phandles to the reference clock and the bus clock
8 - clock-names: Should be "phy_ref_clk" for the reference clock and "apb_pclk"
10 - interrupt-parent: Should be the phandle for the interrupt controller
11 that services interrupts for this device
12 - interrupts: Should contain the core's combined interrupt signal
13 - phy-mode: See ethernet.txt file in the same directory
16 - dma-coherent: Present if dma operations are coherent
17 - mac-address: See ethernet.txt in the same directory
18 - local-mac-address: See ethernet.txt in the same directory
19 - snps,en-lpi: If present it enables use of the AXI low-power interface
20 - snps,write-requests: Number of write requests that the AXI port can issue.
21 It depends on the SoC configuration.
22 - snps,read-requests: Number of read requests that the AXI port can issue.
23 It depends on the SoC configuration.
24 - snps,burst-map: Bitmap of allowed AXI burst lengts, with the LSB
25 representing 4, then 8 etc.
26 - snps,txpbl: DMA Programmable burst length for the TX DMA
27 - snps,rxpbl: DMA Programmable burst length for the RX DMA
28 - snps,en-tx-lpi-clockgating: Enable gating of the MAC TX clock during
30 - phy-handle: See ethernet.txt file in the same directory
31 - mdio device tree subnode: When the GMAC has a phy connected to its local
32 mdio, there must be device tree subnode with the following
34 - compatible: Must be "snps,dwc-qos-ethernet-mdio".
35 - #address-cells: Must be <1>.
36 - #size-cells: Must be <0>.
38 For each phy on the mdio bus, there must be a node with the following
41 - reg: phy id used to communicate to phy.
42 - device_type: Must be "ethernet-phy".
43 - fixed-mode device tree subnode: see fixed-link.txt in the same directory
