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