From f71ddc5873cb90ffb217de50aed8bdd2fb00fc9f Mon Sep 17 00:00:00 2001 From: Alexandru M Stan Date: Mon, 12 Oct 2015 14:48:29 +0200 Subject: [PATCH] ARM: dts: rockchip: Add drive/sample clocks for rk3288 dw_mmc devices 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.
