Please also consider queuing up the attached patch as well.

The patch is removing the current SDIO cards 1.8V limit, which is
needed for embedded
SDIO devices like TI 127x WLAN devices (with 1.8V MMC controllers like we
have on the ZOOM2 boards for example).

Thank you,
Ohad.

This is needed for 1.8V embedded SDIO devices and supporting host controllers
(e.g. TI 127x and ZOOM2 boards)
