The device node has following properties.
Required properties:
- compatible: Should be "st,stm32-dwmac" to select glue, and
- 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 and,
"syscfg-clk" for SYSCFG 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.
encompases the glue register, and the offset of the control register.
Optional properties:
- clock-names: For MPU family "mac-clk-ck" for PHY without quartz
- st,int-phyclk (boolean) : valid only where PHY do not have quartz and need to be clock
