Subject: [PATCH 1/2] Documentation: mmc: sdhci-of-arasan: add description of power domain
Date: Sat, 27 Aug 2016 21:41:02 +0800 [thread overview]
Message-ID: <20160827134103.28160-2-xzy.xu@rock-chips.com> (raw)
In-Reply-To: <20160827134103.28160-1-xzy.xu@rock-chips.com>
Add power domain as a optional property for sdhci-of-arasan, which can
be truned off in the so-called unused condition, such as suspend and
remove. Aim to lower power requirements.
