| 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"; | |
| 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; | |
| }; |
