I generally perform my tests with omap2plus_defconfig and without this series MMC doesn't work with omap2plus_defconfig. > > Kishon, could you please clarify if $subject patchset solves that > regression reported by Olof? Or perhaps Olof can run a test? Just checked multi_v7_defconfig and this series is definitely required to get MMC working. But we also have to enable 'CONFIG_REGULATOR_PBIAS' which is not enabled by default in multi_v7_defconfig. So we should have a patch to enable 'CONFIG_REGULATOR_PBIAS' in multi_v7_defconfig to completely solve the problem reported by Olof. I'll prepare a patch for multi_v7_defconfig and post it asap.
