Please include following patch from Linus' tree in the 3.18 branch.
Without it SDHC is unusable on Freescale P2020.  Thanks!

mmc: sdhci: Fix FSL ESDHC reset handling quirk

The commit 0718e59ae259 ("mmc: sdhci: move FSL ESDHC reset handling quirk into
esdhc code") states that Freescale esdhc is the only controller which needs
the interrupt registers restored after a reset. So it moves
SDHCI_QUIRK_RESTORE_IRQS_AFTER_RESET quirk handling code into the
esdhc-imx driver only. Unfortunately the same controller is used in
other boards which use the of-esdhc driver instead (like powerpc P2020).

Restore interrupts after reset in the sdhci-of-esdhc driver also.

I don't see this commit anywhere in Linus's tree.  Where did you find
it?

thanks,

Argh, stupidly I sent you the commit id from after I applied this to
3.18...  In Linus's tree it's 304f0a98d168, sorry.

I don't remember tree what you wanted this applied to, so I tried
3.14-stable, and that didn't work.  Can you be more specific?

thanks,

OK, let me try again.  I would like the following commit to be applied
to 3.18:

As I don't maintain 3.18, nothing I can do here, great! :)

It looks like this fix is also applicable to the 3.16 kernel.  I'll
queue it for the next release.
