-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: For MCU family should be "st,stm32-dwmac" to select glue, and
- "snps,dwmac-3.50a" to select IP version.
- For MPU family should be "st,stm32mp1-dwmac" to select
- glue, and "snps,dwmac-4.20a" 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.
- For MPU family need to add also "ethstp" for power mode clock
-- interrupt-names: Should contain a list of interrupt names corresponding to
- the interrupts in the interrupts property, if available.
- Should be "macirq" for the main MAC IRQ
- Should be "eth_wake_irq" for the IT which wake up system
-- 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.
-
-Optional properties:
-- clock-names: For MPU family "eth-ck" for PHY without quartz
-- st,eth-clk-sel (boolean) : set this property in RGMII PHY when you want to select RCC clock instead of ETH_CLK125.
-- st,eth-ref-clk-sel (boolean) : set this property in RMII mode when you have PHY without crystal 50MHz and want to select RCC clock instead of ETH_REF_CLK.
-
-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;
- };
