Subject: [PATCH v2 8/9] mmc: dw_mmc-pltfm: deploy runtime PM facilities
Date: Wed, 12 Oct 2016 10:56:46 +0800	[thread overview]
Message-ID: <1476241006-5891-1-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1476240643-5701-1-git-send-email-shawn.lin@rock-chips.com>

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.

Signed-off-by: Shawn Lin <shawn.lin@rock-chips.com>

Changes in v2:
- use dw_mci_runtime_* directly
