-IMX8 glue layer controller, NXP imx8 families support Synopsys MAC 5.10a IP.
-
-This file documents platform glue layer for IMX.
-Please see stmmac.txt for the other unchanged properties.
-
-The device node has following properties.
-
-Required properties:
-- compatible:  Should be "nxp,imx8mp-dwmac-eqos" to select glue layer
-	       and "snps,dwmac-5.10a" 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 "pclk" for the MAC apb clock.
-	       Should be "ptp_ref" for the MAC timer clock.
-	       Should be "tx" for the MAC RGMII TX clock:
-	       Should be "mem" for EQOS MEM clock.
-		- "mem" clock is required for imx8dxl platform.
-		- "mem" clock is not required for imx8mp platform.
-- 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
-- intf_mode: Should be phandle/offset pair. The phandle to the syscon node which
