Thanks for reporting this. I'm not sure but it seems that relevant to my fixing 
patch.

mmc: fix the wrong disabling clock

When power is off, clock is not disabling.
Because it's passed to 1, mmc->clock should be set to f_min value.
Some drivers can't initialize the eMMC/SD card with current status.

This patch is to fix the disabling clock value to 0.

Fixes: 2e7410d76ad1 ("mmc: disable the mmc clock during power off")

[U-Boot] u-boot-mmc fails on almost every Tegra board

2018-01-22 Thread Stephen Warren 

Jaehoon,

The latest commit in u-boot-mmc.git master branch fails on almost every 
Tegra board. The MMC device experiences an error during initialization 
and hence isn't available:
