+ * (also known as PL180) block.
+ * @ocr_mask: available voltages on the 4 pins from the block, this
+ * is ignored if a regulator is used, see the MMC_VDD_* masks in
+ * mmc/host.h
+ * @ios_handler: a callback function to act on specfic ios changes,
+ * used for example to control a levelshifter
+ * 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 read function was given to the block in
+ * gpio_wp (below) this function will be called to determine
+ * whether a card is present in the MMC slot or not
+ * @gpio_wp: read this GPIO pin to see if the card is write protected
+ * @gpio_cd: read this GPIO pin to detect card insertion
+ * @cd_invert: true if the gpio_cd pin value is active low
