| * @wprotect_invert: Invert the default sense of the write protect switch. |
| * @use_dma: Set to allow the use of DMA. |

| * @gpio_wprotect: GPIO number for the write protect line. |
| * @ocr_avail: The mask of the available power states, non-zero to use. |
| * @set_power: Callback to control the power mode. |
| * |
| * The @gpio_detect is used for card detection when @no_wprotect is unset, |
| * and the default sense is that 0 returned from gpio_get_value() means |
| * that a card is inserted. If @detect_invert is set, then the value from |
| * gpio_get_value() is inverted, which makes 1 mean card inserted. |
| * |
| * The driver will use @gpio_wprotect to signal whether the card is write |
| * protected if @no_wprotect is not set. A 0 returned from gpio_get_value() |
| * means the card is read/write, and 1 means read-only. The @wprotect_invert |
| * will invert the value returned from gpio_get_value(). |
| * |
| * Card power is set by @ocr_availa, using MCC_VDD_ constants if it is set |
| * to a non-zero value, otherwise the default of 3.2-3.4V is used. |
