1STMicroelectronics STM32 / MCU DWMAC glue layer controller
2
3This file documents platform glue layer for stmmac.
4Please see stmmac.txt for the other unchanged properties.
5
6The device node has following properties.
7
8Required properties:
9- compatible: Should be "st,stm32-dwmac" to select glue, and
10 "snps,dwmac-3.50a" to select IP version.
11- clocks: Must contain a phandle for each entry in clock-names.
12- clock-names: Should be "stmmaceth" for the host clock.
13 Should be "mac-clk-tx" for the MAC TX clock.
14 Should be "mac-clk-rx" for the MAC RX clock.
15- st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
16 encompases the glue register, and the offset of the control register.
17Example:
18
19 ethernet@40028000 {
20 compatible = "st,stm32-dwmac", "snps,dwmac-3.50a";
21 status = "disabled";
22 reg = <0x40028000 0x8000>;
23 reg-names = "stmmaceth";
24 interrupts = <0 61 0>, <0 62 0>;
25 interrupt-names = "macirq", "eth_wake_irq";
26 clock-names = "stmmaceth", "mac-clk-tx", "mac-clk-rx";
27 clocks = <&rcc 0 25>, <&rcc 0 26>, <&rcc 0 27>;
28 st,syscon = <&syscfg 0x4>;
29 snps,pbl = <8>;
30 snps,mixed-burst;
31 dma-ranges;
32 };
