  10 * struct mmci_platform_data - platform configuration for the MMCI
  11 * (also known as PL180) block.
  12 * @ocr_mask: available voltages on the 4 pins from the block, this
  13 * is ignored if a regulator is used, see the MMC_VDD_* masks in
  14 * mmc/host.h
  15 * @ios_handler: a callback function to act on specfic ios changes,
  16 * used for example to control a levelshifter
  17 * mask into a value to be binary (or set some other custom bits
  18 * in MMCIPWR) or:ed and written into the MMCIPWR register of the
  19 * block.  May also control external power based on the power_mode.
  20 * @status: if no GPIO read function was given to the block in
  21 * gpio_wp (below) this function will be called to determine
  22 * whether a card is present in the MMC slot or not
  23 * @gpio_wp: read this GPIO pin to see if the card is write protected
  24 * @gpio_cd: read this GPIO pin to detect card insertion
  25 * @cd_invert: true if the gpio_cd pin value is active low
