Two AD9361 with separated SPI interface

we have developed a custom board with two AD9361 and a Z7020 SoC. The design is related to the ZC702+FMCOMMS5. Unfortunately, the hardware designer has implemented two separated SPI interface for each AD9361 instead of using the bus design from the FMCOMMS5. In HDL we were able to multiplex/combine these signals, but I guess that something on the drivers side oder devicetree has to be modified as well. Could you confirm that?


what do we have to modify to use the same functions like the basic design of the FMCOMMS5.


thanks and kindly regards
