First, i found that this patch didn't initialize the values from device-tree.
It is called power_board_init -> exynos_power_init()
In exnyos_power_init(), there is no code relevant to "s2mps11_pmic".

pmic_get("s2mps11_pmic", &dev);

and need to implement the others..

Second, it seems that there is a bug on mmc side about "mmc_init: -110, time 80".

Will send the patch about all things.
