I did this test now.

After commit c10d1e2, CONFIG_OLPC selects CONFIG_OF, which enables to
select CONFIG_MMC_SDHCI_OF, which does not build on x86:

Since mmc clock gating is done in a work queue which is not synchronized with
host runtime power management, when driver is doing clock gating, host may
has already been power gated.
So before driver clock gate host, check whether host is already suspended.

MMC host need to power ungate host each time before sending a request and
try to power gate host each time after the request is done.
MMC host has a sysfs interface to let user specify the auto suspended delay.
Each slot of the host controller can have a different delay for runtime
suspended.

Hi all,
These are the version 1 patches for enabling runtime power management for
mmc host driver stack.
Right now runtime pm in mmc driver stack can only care about the
power of SDIO card, not the host controller. Host controller also needs
runtime pm to save power.
