Date: Fri, 22 Jan 2016 12:35:26 +0800 From: "Fu, Zhonghui" <zhonghui.fu@...ux.intel.com> To: Ulf Hansson <ulf.hansson@...aro.org> Cc: Adrian Hunter <adrian.hunter@...el.com>, michele.curti@...il.com, linux-mmc <linux-mmc@...r.kernel.org>, linux-kernel@...r.kernel.org Subject: [PATCH 2/2 v2] mmc/sdhci-acpi: enable sdhci-acpi device to suspend/resume asynchronously This patch enables sdhci-acpi devices to suspend/resume asynchronously. This will 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 1089ms, and the system resume time is reduced from 940ms to 908ms.
