The commit abd7d0972a192 ("arm64: dts: hikey: Enable HS200 mode on
eMMC") can work well on my Hikey620 board, my Hikey620 board is
Lemaker version with 8GB Samsung emmc flash.

John, are you using different Hikey manufacturing version?

Thanks to report this!
Let me check with Leo and Guodong to know which property changing
this is caused by.

Hi Leo and Guodong,

Can you help to confirm the commit abd7d0972a192?

Thanks to report this!
Let me check with Leo and Guodong to know which property changing
this is caused by.

Hi Leo and Guodong,

Can you help to confirm the commit abd7d0972a192?

REGRESSION: HiKey eMMC corruption

[John Stultz]

The last few months have been busy and I've not been ontop of my
upstream testing as well as I'd like, but today I did manage to chase
down an issue I've been seeing since 4.17-rc1 on the HiKey board,
which was causing emmc corruption and stopping the board from booting.

Symptoms usually looked like:

And quite often this would result in a disk that wouldn't properly
boot even with older kernels.

I've narrowed the issue down to the following change:
abd7d0972a192 ("arm64: dts: hikey: Enable HS200 mode on eMMC")

Reverting this change seems to make things work reliably for me.

Should we revert that upstream for now?

And quite often this would result in a disk that wouldn't properly
boot even with older kernels.

I've narrowed the issue down to the following change:
abd7d0972a192 ("arm64: dts: hikey: Enable HS200 mode on eMMC")

Reverting this change seems to make things work reliably for me.

Should we revert that upstream for now?
