Subject: [PATCH] dts: am335x-pdu001: Fix polarity of card detection input
When a micro SD card is inserted in the PDU001 card cage, the card
detection switch is opened and the corresponding GPIO input is driven
by a pull-up. Hence change the active level of the card detection
input from low to high.
