Subject: [PATCH 1/5] Documentation: mmc: synopsys-dw-mshc: add power domain description
Date: Fri, 29 Jul 2016 12:14:59 +0800 [thread overview]
Message-ID: <1469765703-30999-2-git-send-email-shawn.lin@rock-chips.com> (raw)
In-Reply-To: <1469765703-30999-1-git-send-email-shawn.lin-TNX95d0MmH7DzftRWevZcw@public.gmane.org>
This patch adds power domain as a optional property for dw_mmc.
We should handle the power domain if available as it's in off
state dut to the policy of power-saving after booting up. Otherwise
dw_mmc can not be accessed.
