From mboxrd@z Thu Jan 1 00:00:00 1970 From: Shawn Lin Subject: [PATCH v2 8/9] mmc: dw_mmc-pltfm: deploy runtime PM facilities Date: Wed, 12 Oct 2016 10:56:46 +0800 Message-ID: <1476241006-5891-1-git-send-email-shawn.lin@rock-chips.com> References: <1476240643-5701-1-git-send-email-shawn.lin@rock-chips.com> Return-path: In-Reply-To: <1476240643-5701-1-git-send-email-shawn.lin@rock-chips.com> Sender: linux-mmc-owner@vger.kernel.org To: Jaehoon Chung , Ulf Hansson Cc: linux-mmc@vger.kernel.org, Doug Anderson , linux-rockchip@lists.infradead.org, Shawn Lin List-Id: linux-rockchip.vger.kernel.org Let's migrate it to use runtime PM and remove the system PM callback from this driver. With this patch, it could handle system PM properly and could also use runtime PM if we enable it.
