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. After enabling the sdhci-acpi devices and all their child devices to suspend/resume asynchronously on ASUS T100TA, the system suspend-to-idle time is reduced from 1645ms to 1096ms, and the system resume time is reduced from 940ms to 908ms.
