Yeah, both are there but it is muxed by the bootloader using a GPIO. For
icicle this is done by a mux in the FPGA fabric instead. Tw dts were
needed so that the gpio-hog could be set correctly. Out of curiosity, I can
have the same compatible in multiple devicetrees right? In that case, it
would just be "aries,m100pfsevp" here and I could put that in both?
Would make things easier..

Gah, that's a silly one to miss..
