Help! after go to deep sleep mode, eMMC consumes more power than idle.

Hi All,

I am on a tablet project, and I encountered a very strange bug:

After the tablet goes to deep sleep mode, the eMMC consumes more power than idle.

idle with display on: 2.7 mw
deep sleep: 9.2 mw

I have checked lots of places in the kernel, but I didn't find anything.

Can anyone give me some suggestion? Where should I focus to figure this out?

Big thanks!!!

Anyone can help? I am getting crazy.
