It has been discovered that, when eMMC is powered off, current will flow from OMAP eMMC data pull-ups to the eMMC voltage supply. Configuring pads for OMAP off-mode does not help because eMMC is powered off independently of OMAP off-mode. Hence the pads are now re-configured when eMMC is powered on or off.
