Sorry i have to make a correction here: wifi works. It didn't just
because this board has hardware design issues even reported in the d-link
sources regarding wifi... basically, to make it work i have to 
enable wifi 5Ghz, enable wifi 2Ghz, then if i want 5Ghz i have to
disable wifi 2Ghz, disable 5Ghz and re-enable 5Ghz. yes it's a mess.


Anyway, wifi works. It just probably happened i accidentally got
the right sequence when doing my tests when ethernet was also
working.


so back to the pinctrl/pinmux theory i guess. 
The cpu and switch ports are set to mii. i tried to set
the cpu port to a fixed-link 100Mbps but it doesn't make a difference
tried also most other mii variants to no avail.
