This series is named as "Attempt to enable MMC on SpacemiT K1 boards", what's the relationship between MMC and PMIC/I2C bus? You didn't make use of any regulators in the second patch, either (which seems wrong to me). vmmc-supply specifies the card's power supply. And if you want to enable SDR modes which mandate 1.8v IO level, vqmmc-supply is also necessary for switching between 1.8v and 3.3v.
