From fa663c7db49204dcfa91666278b210695629df13 Mon Sep 17 00:00:00 2001 From: Haibo Chen Date: Fri, 27 Feb 2015 18:35:30 +0800 Subject: MLK-10237-4 mmc: sdhci-esdhc-imx: add tuning-step setting support tuning-step is the delay cell steps in tuning procedure. This patch add the tuning-step setting in driver, so that user can set the tuning-step value in dts. e.g. tuning-step = <2>; this example set the tuning-step as value 2. This patch also set the tuning-step of i.MX7D as 2, so that the tuning procedure can execute successfully.
