config MMC_BLOCK
	tristate "MMC block device driver"
	depends on BLOCK
	default y
	help
	  Say Y here to enable the MMC block device driver support.
	  This provides a block device driver, which you can use to
	  mount the filesystem. Almost everyone wishing MMC support
	  should say Y or M here.

config SNSC_MMC_MMC_SHIFT
        int "Value of MMC_SHIFT"
	depends on MMC
        range 0 8
        default 3
        help
          Select MMC_SHIFT which defines the number of supported MMC/SD devices
          and partitions per a device.

            - the number of supported devices    = 256 >> MMC_SHIFT
            - the number of supported partitions = 1   << MMC_SHIFT

          Examples:
                     3 => 32 devices, 8 partitions
                     4 => 16 devices, 16 partitions

config MMC_BLOCK_BOUNCE
	bool "Use bounce buffer for simple hosts"
	depends on MMC_BLOCK
	default y
	help
	  SD/MMC is a high latency protocol where it is crucial to
	  send large requests in order to get high performance. Many
	  controllers, however, are restricted to continuous memory
	  (i.e. they can't do scatter-gather), something the kernel
	  rarely can provide.

	  Say Y here to help these restricted hosts by bouncing
	  requests back and forth from a large buffer. You will get
	  a big performance gain at the cost of up to 64 KiB of
	  physical memory.

	  If unsure, say Y here.

config SDIO_UART
	tristate "SDIO UART/GPS class support"
	depends on MMC
	help
	  SDIO function driver for SDIO cards that implements the UART
	  class, as well as the GPS class which appears like a UART.

config SNSC_MMC_WRITE_RETRY
	bool "Retry on write failure"
	depends on SNSC
	default n

config SNSC_MMC_WRITE_RETRY_MAX_COUNT
	int "Maximum number of write retries"
	depends on SNSC_MMC_WRITE_RETRY
	default 1
