Stefan Roese6a228452012-03-13 04:56:37 +00001* STMicroelectronics 10/100/1000 Ethernet driver (GMAC)
2
3Required properties:
Dinh Nguyen84c9f8c42012-07-18 13:28:26 +00004- compatible: Should be "snps,dwmac-<ip_version>" "snps,dwmac"
5 For backwards compatibility: "st,spear600-gmac" is also supported.
Stefan Roese6a228452012-03-13 04:56:37 +00006- reg: Address and length of the register set for the device
7- interrupt-parent: Should be the phandle for the interrupt controller
8 that services interrupts for this device
9- interrupts: Should contain the STMMAC interrupts
10- interrupt-names: Should contain the interrupt names "macirq"
11 "eth_wake_irq" if this interrupt is supported in the "interrupts"
12 property
13- phy-mode: String, operation mode of the PHY interface.
14 Supported values are: "mii", "rmii", "gmii", "rgmii".
Srinivas Kandagatla25c83b52013-07-04 10:35:41 +010015- snps,phy-addr phy address to connect to.
Srinivas Kandagatla0e076472013-07-04 10:35:48 +010016- snps,reset-gpio gpio number for phy reset.
17- snps,reset-active-low boolean flag to indicate if phy reset is active low.
18- snps,reset-delays-us is triplet of delays
19 The 1st cell is reset pre-delay in micro seconds.
20 The 2nd cell is reset pulse in micro seconds.
21 The 3rd cell is reset post-delay in micro seconds.
Srinivas Kandagatla25c83b52013-07-04 10:35:41 +010022- snps,pbl Programmable Burst Length
23- snps,fixed-burst Program the DMA to use the fixed burst mode
24- snps,mixed-burst Program the DMA to use the mixed burst mode
Sonic Zhange2a240c2013-08-28 18:55:39 +080025- snps,force_thresh_dma_mode Force DMA to use the threshold mode for
26 both tx and rx
27- snps,force_sf_dma_mode Force DMA to use the Store and Forward
28 mode for both tx and rx. This flag is
29 ignored if force_thresh_dma_mode is set.

31Optional properties:
32- mac-address: 6 bytes, mac address
Chen-Yu Tsaic5e4ddb2014-01-17 21:24:41 +080033- resets: Should contain a phandle to the STMMAC reset signal, if any
34- reset-names: Should contain the reset signal name "stmmaceth", if a
35 reset phandle is given
