      For SDIO there are three modes of operation,

      1) 1 bit mode

      2) 4 bit mode

      3) spi mode

      i am able to switch between 1 bit mode and 4 bit mode using quirks_debug value passing with sdhci driver module.but i am not getting how to switch in SPI mode there are no bit are available in driver for setting it to SPI mode. so how to switch in SPI mode ?
