* @ocr_mask: available voltages on the 4 pins from the block, this

* mmc/host.h
* @ios_handler: a callback function to act on specfic ios changes,

* mask into a value to be binary (or set some other custom bits
* in MMCIPWR) or:ed and written into the MMCIPWR register of the
* block. May also control external power based on the power_mode.
* @status: if no GPIO line was given to the block in this function will
* be called to determine whether a card is present in the MMC slot or not
