Thanks for this clean-up.
Speaking about AXS10x board where we do have DW GMAC
I cannot recall the reason I chose to use "altr,socfpga-stmmac"
for the board here  3 years ago.
But given we don't have any special quirks implemented whatever
is the most generic DW GMAC compatible string is should be good for us.
Joe, could you please suggest if we need to use just "st,stm32-dwmac"
or add our own compatible as the ASIC is not from ST obviously but
an FPGA with Synopsys ARC SoC?
