[PATCH 2/4] mmc: sdhci-esdhc-imx: Fix DAT line software reset

2017-05-03 Thread Benoît Thébaudeau
On i.MX25, the eSDHC DAT line software reset (SYSCTL.RSTD) unexpectedly clears at least the data transfer width (PROCTL.DTW), which then results in data CRC errors. This behavior is not documented, but it has actually been observed. Consequently, the DAT line software resets triggered by sdhci.c in
