  10  * struct mmci_platform_data - platform configuration for the MMCI
  11  * (also known as PL180) block.
  12  * @f_max: the maximum operational frequency for this host in this
  13  * platform configuration. When this is specified it takes precedence
  14  * over the module parameter for the same frequency.
  15  * @ocr_mask: available voltages on the 4 pins from the block, this
  16  * is ignored if a regulator is used, see the MMC_VDD_* masks in
  17  * mmc/host.h
  18  * @vdd_handler: a callback function to translate a MMC_VDD_*
  19  * mask into a value to be binary (or set some other custom bits
  20  * in MMCIPWR) or:ed and written into the MMCIPWR register of the
  21  * block.  May also control external power based on the power_mode.
  22  * @status: if no GPIO read function was given to the block in
  23  * gpio_wp (below) this function will be called to determine
  24  * whether a card is present in the MMC slot or not
  25  * @gpio_wp: read this GPIO pin to see if the card is write protected
  26  * @gpio_cd: read this GPIO pin to detect card insertion
  27  * @capabilities: the capabilities of the block as implemented in
  28  * this platform, signify anything MMC_CAP_* from mmc/host.h
