I have recently queued another patchset [1] for the mmc omap driver
for 4.3 through my mmc tree for which Olof Johansson reported a
regression [2] for Panda ES with multi_v7_defconfig.

Kishon, could you please clarify if $subject patchset solves that
regression reported by Olof? Or perhaps Olof can run a test?

Finally, perhaps it's better if we queue this through my mmc tree
since we would then be able to avoid the regression - if I put
$subject patchset before [1], right? Then I need an ack from Mark for
the regulator patch.
Please tell me if you guys prefer another way.

Kind regards
Uffe
