Hi,

this patchset contains fixes for the mxcmmc driver.

*Patch 1:
fix a rare race condition that breaks a data trasfer when mxcmmc
driver use dma.
To reproduce this error, use mmc as rootfs and start at boot time
a realtime Xenomai application.
The realtime it's not directly related but entropy produced by
ipipe scheduler highlights the problem.
When this event occurs, the mxcmmc watchdog expires,
this cause a read error and application doesn't run.

*Patch 2:
fix the default value for available voltages into mxcmci_probe

Applied to mainline Linux-3.17.0-rc6-next on arch mpc512x.
Tested on mpc5125twr evaluation board

Applied to custom Linux-3.9.4 on arch mpc512x
Tested on a mpc5125 custom board.

Regards,
