You might want to ask your TI support contact for IODelay
recommendations. TRM mentions that pinmuxing must be performed under IO
isolation. There are silicon constraints in DRA7/AM57xx family, which
were not present previously.

Ok. I understand. This might take time...
Since we'd like to have this in for 4.5, what would you recommend?
Should I drop the muxes from this patch set? All the muxes?
Or should we merge this (as it works correctly) in our tests and check
on this later after investigation with TI?

Also, in theory, there might be pins shared between two or more
different functionalities and remuxed during runtime.
Can this kind of thing be supported on AM57x?

This is why I suggested to talk and confirm with TI support contact on
this. I understand the motivation of SoM concept, but this requires some
careful designing around.
