What does nic_clk stand for? If I had to guess, it
has something to do with network. But..
NIC clock is the clock used by AXI, AHB fabric and APB bridges which
connects all the peripherals.
It is named so because the AXI fabric is based on NIC400 IP from ARM
Ok, thanks for clarification.

Btw. can we disable all nodes by default and enable them
in the board dts files?
I would like to have only board specific nodes enabled in dts files
and rest of them in dtsi file
And how do you know which ones are board specific? E.g. I would like
to add our board which is also based on the lan9668. Maybe I don't
want a watchdog (or whatever node). Of course I could use
&watchdog {
status = "disabled";
};
But IMHO opt-in is better. At least thats what we are doing for
the layerscape over on arm64.
