- STMicroelectronics STM32 / MCU DWMAC glue layer controller
- This file documents platform glue layer for stmmac.
- Please see stmmac.txt for the other unchanged properties.
- The device node has following properties.
- Required properties:
- - compatible: Should be "st,stm32-dwmac" to select glue, and
- "snps,dwmac-3.50a" to select IP version.
- - clocks: Must contain a phandle for each entry in clock-names.
- - clock-names: Should be "stmmaceth" for the host clock.
- Should be "mac-clk-tx" for the MAC TX clock.
- Should be "mac-clk-rx" for the MAC RX clock.
- - st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
- encompases the glue register, and the offset of the control register.
- Example:
- ethernet@40028000 {
- compatible = "st,stm32-dwmac", "snps,dwmac-3.50a";
- status = "disabled";
- reg = <0x40028000 0x8000>;
- reg-names = "stmmaceth";
- interrupts = <0 61 0>, <0 62 0>;
- interrupt-names = "macirq", "eth_wake_irq";
- clock-names = "stmmaceth", "mac-clk-tx", "mac-clk-rx";
- clocks = <&rcc 0 25>, <&rcc 0 26>, <&rcc 0 27>;
- st,syscon = <&syscfg 0x4>;
- snps,pbl = <8>;
- snps,mixed-burst;
- dma-ranges;
- };
