Subject: [PATCH v2 2/9] dt-bindings: mmc: sprd: Add another optional clock documentation
Date: Tue,  4 Jun 2019 16:14:22 +0800	[thread overview]
Message-ID: <84abb6b282b1fbce0c39ebd2b42ca4c18118f863.1559635435.git.baolin.wang@linaro.org> (raw)

In-Reply-To: <cover.1559635435.git.baolin.wang@linaro.org>

For some Spreadtrum platforms like SC9860 platform, we should enable another
gate clock '2x_enable' to make the SD host controller work well. Thus add
documentation for this optional clock.
