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: | |
