1 STMicroelectronics STM32 / MCU DWMAC glue layer controller
3 This file documents platform glue layer for stmmac.
4 Please see stmmac.txt for the other unchanged properties.
6 The device node has following properties.
9 - compatible: For MCU family should be "st,stm32-dwmac" to select glue, and
10 "snps,dwmac-3.50a" to select IP version.
11 For MPU family should be "st,stm32mp1-dwmac" to select
12 glue, and "snps,dwmac-4.20a" to select IP version.
13 - clocks: Must contain a phandle for each entry in clock-names.
14 - clock-names: Should be "stmmaceth" for the host clock.
15 Should be "mac-clk-tx" for the MAC TX clock.
16 Should be "mac-clk-rx" for the MAC RX clock.
17 For MPU family need to add also "ethstp" for power mode clock and,
18 "syscfg-clk" for SYSCFG clock.
19 - interrupt-names: Should contain a list of interrupt names corresponding to
20 the interrupts in the interrupts property, if available.
21 Should be "macirq" for the main MAC IRQ
22 Should be "eth_wake_irq" for the IT which wake up system
23 - st,syscon : Should be phandle/offset pair. The phandle to the syscon node which
24 encompases the glue register, and the offset of the control register.
27 - clock-names: For MPU family "mac-clk-ck" for PHY without quartz
28 - st,int-phyclk (boolean) : valid only where PHY do not have quartz and need to be clock
