Subject[PATCH v2] mmc/sdhci-acpi: enable sdhci-acpi device to suspend/resume asynchronously
Now, PM core supports asynchronous suspend/resume mode for devices
during system suspend/resume, and the power state transition of one
device may be completed in separate kernel thread. PM core ensures
all power state transition timing dependency between devices. This
patch enables sdhci-acpi device to suspend/resume asynchronously.
This will take advantage of multicore and improve system
suspend/resume speed.
