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.

Tim,
 Does bcm11351-brt not also suffer from the same bug? If it does can
you pls update the patch to also fix it?

 Thanks,

The BRT and AP boards are similar so it may have the same problem but
I don't have a BRT and wouldn't be able to test any changes to its DTS
file.

Olof - can you pls pull in this patch. This is the bugfix that was
discussed in irc earlier today.

I'm not sure Olof saw your reply.  Olof and Kevin are now on CC.

Nope, applied now. Had to touch it up a bit since we're missing some of the
patches that this was based on for 3.14, but the cd-gpios property is fixed.
