Subject: [PATCH 2/9] dt-bindings: mmc: sprd: Add another optional clock documentation
Date: Mon, 20 May 2019 18:11:55 +0800	[thread overview]
Message-ID: <ee4ad0e7e131e4d639dbf6bd25ad93726648ce1c.1558346019.git.baolin.wang@linaro.org> (raw)
In-Reply-To: <cover.1558346019.git.baolin.wang@linaro.org>
In-Reply-To: <cover.1558346019.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.
