Add support to disconnect the pull-up resistor on CD/DAT[3] (pin 1)
of the card. This may be desired on certain setups of boards,
controllers and embedded sdio devices which do not need the card's
pull-up. As a result, card detection is disabled and power is saved.

Well, sort of:
The patch sets disable_cd for TI wl1271 embedded wlan sdio device on a
ZOOM2 platform.
Since the patch is very board/device specific, we first route it via

To save power, the pull-up resistor on CD/DAT[3] (pin 1)
of the card can be disconnected. This is desired, e.g.,
with embedded SDIO devices which do not rely on this pin
for card detection.

have on the ZOOM2 boards for example).
Thank you,
