Hi Laurent,

Your issue seem more related to a mmc protocol problem. Likely caused
by a bad patch for eMMC 4.5 poweroff notify. The patch I refer to is:
"mmc: core: Fix PowerOff Notify suspend/resume"

You may try to revert this patch and see if the same problem occurs for you.

We are trying to fix the issue inserted by the above commit in a patch
named: "MMC-4.5 Power OFF Notify Rework", please have a look if you have
the time.

I think the two issues are othorgonal (but please feel free to tell me if 
there's something I'm missing).

The MMCIF controller driver rejects the MMC_SLEEP_AWAKE command 
unconditionally, even though it should be accepted, because it happens to 
share the command number with an SDIO command (SD_IO_SEND_OP_COND) used to 
probe SDIO support. My patch fixes this by accepting the MMC_SLEEP_AWAKE 
command but still rejecting the SD_IO_SEND_OP_COND command.
