Okay. If we're going to have two different MV_SDHCI drivers, please coordinate to have different Kconfig entries for the Dove/MMP and MMP2 drivers that correctly identify which SoCs are supported by each, and resend. Neither driver should be called CONFIG_MV_SDHCI, since there will be no one driver for all MV_SDHCIs.
