  8. * struct mmci_platform_data - platform configuration for the MMCI
  9. * (also known as PL180) block.
  10. * @f_max: the maximum operational frequency for this host in this
  11. * platform configuration. When this is specified it takes precedence
  12. * over the module parameter for the same frequency.
  13. * @ocr_mask: available voltages on the 4 pins from the block, this
  14. * is ignored if a regulator is used, see the MMC_VDD_* masks in
  15. * mmc/host.h
  16. * @vdd_handler: a callback function to translate a MMC_VDD_*
  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. * @capabilities: the capabilities of the block as implemented in
  26. * this platform, signify anything MMC_CAP_* from mmc/host.h
