24  * mmc/host.h
25  * @ios_handler: a callback function to act on specfic ios changes,
26  * used for example to control a levelshifter
27  * mask into a value to be binary (or set some other custom bits
28  * in MMCIPWR) or:ed and written into the MMCIPWR register of the
29  * block.  May also control external power based on the power_mode.
30  * @status: if no GPIO read function was given to the block in
31  * gpio_wp (below) this function will be called to determine
32  * whether a card is present in the MMC slot or not
33  * @gpio_wp: read this GPIO pin to see if the card is write protected
34  * @gpio_cd: read this GPIO pin to detect card insertion
35  * @cd_invert: true if the gpio_cd pin value is active low
