From 1194be8c949b8190b2882ad8335a5d98aa50c735 Mon Sep 17 00:00:00 2001 From: Haibo Chen Date: Tue, 26 May 2020 18:22:01 +0800 Subject: mmc: sdhci-esdhc-imx: fix the mask for tuning start point According the RM, the bit[6~0] of register ESDHC_TUNING_CTRL is TUNING_START_TAP, bit[7] of this register is to disable the command CRC check for standard tuning. So fix it here.
