I've taken the updated versions of the I2C patches,
and fixed them not to break omap3_defconfig.

I've picked up these too.
> - The patches 4,5 adds card detect feature for MMC1
I only took 1 - 3 out of the MMC patches, it's too
late to start changing the other stuff.
I've reposted the whole series for a quick review.
FYI, the MMC on omap4 is not quite there yet at least
on my board. It mostly detects the card with
omap_4430sdp_defconfig, but fails always unless
CONFIG_RTC_DRV_TWL92330=y.. This is without CONFIG_SMP
as it oopses.
Hope you are referring CONFIG_RTC_DRV_TWL92330 to omap3_defconfig
and not to omap_4430sdp_defconfig.
With omap_4430sdp_defconfig , I've tested on 4430SDP and Blaze and always
Cards on MMC1 & MMC2 gets detected once bootedup.
Also MMC is never detected with omap3_defconfig.
With omap3_defconfig + disabling "CONFIG_OMAP_RESET_CLOCKS",
I've tested on 4430SDP and Blaze and always Cards on MMC1 & MMC2
gets detected on bootup.
Santosh & Kishore, maybe take a look at that, otherwise
it looks like we still don't have a very usable support
for omap4.
I've piled all these patches into linux-omap master branch
for easy testing. Let me know if I missed some patch.
Following is the commit ID :1674c0ceabfb7726246989874bb4da7bcb55ea89
used on LO master branch for testing. All the patches were merged.

Kishore
