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 * @translate_vdd: a callback function to translate a MMC_VDD_*
19 * mask into a value to be binary or:ed and written into the
20 * MMCIPWR register of the block
21 * @status: if no GPIO read function was given to the block in
22 * gpio_wp (below) this function will be called to determine
23 * whether a card is present in the MMC slot or not
24 * @gpio_wp: read this GPIO pin to see if the card is write protected
25 * @gpio_cd: read this GPIO pin to detect card insertion
26 * @capabilities: the capabilities of the block as implemented in
27 * this platform, signify anything MMC_CAP_* from mmc/host.h
