Subject: [PATCH] ARM: dts: bcm28155-ap: Fix Card Detection GPIO
Date: Thu, 14 Nov 2013 10:07:30 -0800 [thread overview]
Message-ID: <1384452450-26308-1-git-send-email-tim.kryger@linaro.org> (raw)
The board schematic states that the "SD_CARD_DET_N gets pulled to GND
when card is inserted" so the polarity has been updated to active low.
Polarity is now specified with a GPIO define instead of a magic number.
