 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

+- 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
