/**
* struct mmci_platform_data - platform configuration for the MMCI
* (also known as PL180) block.
* @f_max: the maximum operational frequency for this host in this
* platform configuration. When this is specified it takes precedence
* over the module parameter for the same frequency.
* @ocr_mask: available voltages on the 4 pins from the block, this
* is ignored if a regulator is used, see the MMC_VDD_* masks in
* mmc/host.h
* @translate_vdd: a callback function to translate a MMC_VDD_*
* mask into a value to be binary or:ed and written into the
* MMCIPWR register of the block
* @status: if no GPIO read function was given to the block in
* gpio_wp (below) this function will be called to determine
* whether a card is present in the MMC slot or not
* @gpio_wp: read this GPIO pin to see if the card is write protected
* @gpio_cd: read this GPIO pin to detect card insertion
* @capabilities: the capabilities of the block as implemented in
* this platform, signify anything MMC_CAP_* from mmc/host.h
