Hi all,
This is a RFC patch that support clock-gating for saving power consumption.
I found mmc_host_enable/mmc_host_disable function in core.c
(using MMC_CAP_DSIABLE. i think that use when host enable/disable)
So, i used that functions and implemented some functions in sdhci-s3c.c &
sdhci

Some hardware has restrictions that require only one command is outstanding
per controller or some other similar restriction.
Provide optional serialization support and enable it for the Intel MID
platform devices with this restriction. Split up from some existing patches
by JiebingLi.

The Intel MID platforms need various workarounda and helpers. This series of
patches introduces two things
- A set of overrides for basic operations (as opposed to yet more quirk flags)
- The supporting logic to propogate those new operations through the PCI sdhci
code as far as is needed in eac

Since the driver is for controllers integrated into Marvells SoCs only
offer MMC_SDHCI_MV if we're building for one.
