/**
* struct mmci_platform_data - platform configuration for the MMCI
* (also known as PL180) block.
* @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
* @ios_handler: a callback function to act on specfic ios changes,
* used for example to control a levelshifter
* mask into a value to be binary (or set some other custom bits
* in MMCIPWR) or:ed and written into the MMCIPWR register of the
* block. May also control external power based on the power_mode.
* @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
* @cd_invert: true if the gpio_cd pin value is active low
