Hello
I wonder if you could review the three patches I sent the mailing list:
especially the following ones:

mmc: add suspend/resume in the sdhci-pltfm driver
mmc: split the sdhci.h to help platforms that uses shdci-pltfm d.d.

These follow the advice discussed with Wolfram in the thread named:
  "[PATCH] mmc: add SDHCI driver for STM platforms (V2)."

I just noticed to have forgotten to put in cc Andrew and Matt (sorry).

In fact, I want to remove the stm driver and use the pltfm driver
instead of. To do that on my platforms, I need have the support provided
in these patches. This support could actually be useful for others.

Let me know.

Best Regards,
Peppe
