From d87fc96636884430278bc3b425a5a6e2c071a377 Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Tue, 12 Jul 2016 15:46:15 +0800 Subject: mmc: sdhci-esdhc-imx: support setting tuning start point The delay cells of some SoCs may have less delay per one cell, for such SoCs, user could set the start delay cell point to bypass the first a few meaningless tuning commands.
