+/**
+ * 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
