Cynerd opened a new pull request, #8577:
URL: https://github.com/apache/nuttx/pull/8577

   The original code hard-coded card detection to the low when card is inserted 
and high when not. This might not be true on every board because it depends on 
the slot and wiring used. The second reason is because it is also possible to 
detect card with D3 pin pull-up when the slot does not provide dedicated card 
detection switch.
   
   This introduces new argument to the sam_hsmci_initialize to allow invert of 
card detection pin. It also applies this invert to existing boards as that was 
the state up to this point.
