1 | STMicroelectronics STM32 / MCU DWMAC glue layer controller |
| 2 | ||
| 3 | This file documents platform glue layer for stmmac. | |
| 4 | Please see stmmac.txt for the other unchanged properties. | |
| 5 | ||
| 6 | The device node has following properties. | |
| 7 | ||
| 8 | Required 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. | |
| 17 | Example: | |

| 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>; | |
