When using my stripped version of kernel (3.18.9), the MMC0 will
sometimes complain unrecognized SCR structure... when a microSD is

I think we need an generic approach to deal with the runtime PM
synchronization issue described above. More precisely in those
scenarios when mmc hosts needs to notify the

Here is V3 of some patches to move re-tuning support
out of sdhci and into the core, and add support for HS400

Currently sdhci does re-tuning transparently by
calling sdhci_execute_tuning() from

Some versions of this controller do not advertise their 3.0v and
8bit bus-width support capabilities. It is required to explicitly
set these capabilities for the specific controller versions.

Which I resolved using runtime get / put calls.
Returning -EBUSY from runtime suspend, on the other hand, seems
less than ideal.

For Neil's problem I would do something quiet different:
1. The host driver already knows the bus width so can easily get/put
runtime pm to prevent suspend when the bus width does not permit it.
