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 "ethstp" for power mode clock.
+ For MPU family need also "syscfg-clk" for SYSCFG clock.
+- interrupt-names: Should contain a list of interrupt names corresponding to
+ the interrupts in the interrupts property, if available.
- 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 : valid only where PHY do not have quartz and need to be clock
+ by RCC
