10 * struct mmci_platform_data - platform configuration for the MMCI
11 * (also known as PL180) block.
Linus Walleij808d97c2010-04-08 07:39:38 +010012 * @ocr_mask: available voltages on the 4 pins from the block, this
13 * is ignored if a regulator is used, see the MMC_VDD_* masks in
14 * mmc/host.h
Ulf Hanssonbc521812011-12-13 16:57:55 +010015 * @ios_handler: a callback function to act on specfic ios changes,
16 * used for example to control a levelshifter
Rabin Vincentbb8f5632010-07-21 12:53:57 +010017 * mask into a value to be binary (or set some other custom bits
18 * in MMCIPWR) or:ed and written into the MMCIPWR register of the
19 * block. May also control external power based on the power_mode.
Linus Walleij808d97c2010-04-08 07:39:38 +010020 * @status: if no GPIO read function was given to the block in
21 * gpio_wp (below) this function will be called to determine
22 * whether a card is present in the MMC slot or not
23 * @gpio_wp: read this GPIO pin to see if the card is write protected
24 * @gpio_cd: read this GPIO pin to detect card insertion
Rabin Vincent29719442010-08-09 12:54:43 +010025 * @cd_invert: true if the gpio_cd pin value is active low
