There was a problem hiding this comment.
Changes make sense.
I also compared the new pins assignment against SAME54-XPRO user manual.
Looks like this is all good.

Contribution description
Attaching the
at86rf215reference module to asame54-xpro(via EXT1) stops working after 2a255ff configured the PHY IRQ pin to produce interrupts.This is because both the PHY IRQ (PD12) as well as the
at86rf215IRQ (PB07) map to EXI7.Whatever of the two pins gets configured last wins.
Testing procedure
Attach the REB215-XPRO module to EXT3 on
same54-xpro.Frame reception should now work again even if
sam0_ethis in use.Issues/PRs references
