Hi,
After
commit 197160d52e859575ff0ad1afd674ab2a825b9f83

mmc: sdhci: remove mdelay in eMMC tuning
I find Micron eMMC HS200 and HS400 can't pass tuning on i.MX7D platform, here is the log:
[ 2.835581] sdhci: Tuning procedure failed, falling back to fixed sampling clock
[ 2.843071] mmc1: tuning execution failed
[ 2.847104] mmc1: error -5 whilst initialising MMC card
When I revert this commit, issue gone.
I'm not sure whether it is the limitation of Micron eMMC chip, or a common issue.
Does anyone meet the same issue on other platform or on other eMMC chip?
