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 | ||
