Unless you start a _new thread_ for your question and describe your problem in

lazy_disable framework in OMAP HSMMC manages multiple low power states

Based on previous discussion on the list, card power (regulator)
handling (when to power OFF/ON) should ideally be handled by core layer.

Removing the custom state machine - lazy disable framework in omap_hsmmc
to make way for runtime pm to handle host controller
power states.
This allows mmc_host_enable/mmc_host_disable to be replaced by
runtime get_sync and put_sync at host controller driver.
Enable runtime PM in omap_hsmmc
add runtime pm support to HSMMC host controller
Use runtime pm API to enable/disable HSMMC clock
Use runtime autosuspend APIs to enable auto suspend delay

The way the request data is organized in the mmc queue struct
it only allows processing of one request at the time.
This patch adds a new struct to hold mmc queue request data such as
sg list, request, blk request and bounce buffers, and updates any functions
depending on the mmc queue struct.
Break out code from mmc_blk_issue_rw_rq to create a
block request prepare function. This doesn't change
any functionallity. This helps when handling more
than one active block request.

Change mmc_blk_issue_rw_rq() to become asynchronous.
The execution flow looks like this:
The mmc-queue calls issue_rw_rq(), which sends the request
to the host and returns back to the mmc-queue. The mmc-queue calls
issue_rw_rq() again with a new request. This new request is prepared,
in
pre_req() runs dma_map_sg() and prepares the dma descriptor
for the next mmc data transfer. post_req() runs dma_unmap_sg.
If not calling pre_req() before mmci_request(), mmci_request()
will prepare the cache and dma just like it did it before.
