From 9f0e13546ef5773b7059b531a667ec47a5f897ee Mon Sep 17 00:00:00 2001 From: "Fu, Zhonghui" Date: Sat, 19 Sep 2015 10:40:14 +0800 Subject: [PATCH] net/wireless: enable wiphy 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 wiphy device to suspend/resume asynchronously. This can take advantage of multicore and improve system suspend/resume speed.
