Subject: [PATCH v3 6/7] ARM: dts: rockchip: Add drive/sample clocks for rk3288 dw_mmc devices
Date: Mon, 12 Oct 2015 14:48:29 +0200	[thread overview]
Message-ID: <1444654110-32293-7-git-send-email-heiko@sntech.de> (raw)
In-Reply-To: <1444654110-32293-1-git-send-email-heiko@sntech.de>

From: Alexandru M Stan <amstan@chromium.org>

The drive/sample clocks can be phase shifted.  The drive clock
could be used in a future patch to adjust hold times.  The sample
clock is used for tuning.
