| |
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.
