> SDIO frequency was limited to workaround some instabilities, however
> it turned out that the instability had nothing to do with the speed but
> was because of an issue with the USDHC IP that was fixed in commit
> 52e4c32baed2 ("mmc: sdhci-esdhc-imx: only enable DAT[0] and CMD
> line auto tuning for SDIO device").
