Change the handling for the 'abort' flag so that if
it is set, but we can claim the host, then do the claim,
rather than aborting.
When the abort is async this just means that a race between aborting
an allowing a claim is resolved slightly differently. Any
code must already be able to handle
Make use of the new mmc_sdio_want_no_clocks() call to avoid stopping
clocks while SD Card interrupts are enabled and we aren't in
1-bit mode.
Also stop clocks immediately in omap_hsmmc_disable_fclk() if
1-bit mode has been entered for this purpose.
With this, I can use my libertas wifi with a
Every call to sdio_enable_4bit_bus is followed (on success) but a call
to mmc_set_bus_width().
To simplify the code, include those calls directly in
sdio_enable_4bit_bus().

In the case where the interrupt mechanism is used to wake the host while
the card is in a low power state (i.e. no clocks), Both the card and the

This is a new version which moves most of the code into
mmc/core so it is available to all drivers.
I was wrong about not being able to sleep in pm_runtime callbacks.
There are spinlocks, but not the ones I thought they were...
Anyway, I tried switching to 1-bit mode from within the
