Message-ID: <5603978F.8020403@linux.intel.com> Date: Thu, 24 Sep 2015 14:26:23 +0800 From: "Fu, Zhonghui" <zhonghui.fu@...ux.intel.com> To: wsa@...-dreams.de CC: linux-i2c@...r.kernel.org, "linux-kernel@...r.kernel.org" <linux-kernel@...r.kernel.org> Subject: [PATCH v2] i2c: enable i2c 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 i2c device to suspend/resume asynchronously. This will take advantage of multicore and improve system suspend/resume speed.
