Subject: [PATCH v2] mmc/sdhci-acpi: enable sdhci-acpi device to suspend/resume asynchronously
Date: Mon, 21 Sep 2015 14:51:09 +0800 [thread overview]
Message-ID: <55FFA8DD.5020109@linux.intel.com> (raw)
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.
