+- compatible: Should be "st,stm32-dwmac" to select glue, and + "snps,dwmac-3.50a" to select IP vesrion. +- clocks: Should contain the GMAC main clock, and tx clock
+- compatible: Should be "st,stm32-dwmac" to select glue and + "snps,dwmac-3.50a" to select IP version. +- clocks: Must contain an entry for each entry in clock-names.
???
+- clock-names: Should be "stmmaceth" for the host clock.
+ Should be "tx-clk" for the MAC TX clock.
+ Should be "rx-clk" for the MAC RX clock.
+- 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.
+Example:
