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.
