9 * @detect_invert: Invert the default sense of the write protect switch.

14 * @set_power: Callback to control the power mode.
15 *
16 * The @gpio_detect is used for card detection when @no_wprotect is unset,
17 * and the default sense is that 0 returned from gpio_get_value() means
18 * that a card is inserted. If @detect_invert is set, then the value from
19 * gpio_get_value() is inverted, which makes 1 mean card inserted.
20 *
21 * The driver will use @gpio_wprotect to signal whether the card is write
22 * protected if @no_wprotect is not set. A 0 returned from gpio_get_value()
23 * means the card is read/write, and 1 means read-only. The @wprotect_invert
24 * will invert the value returned from gpio_get_value().
25 *
26 * Card power is set by @ocr_availa, using MCC_VDD_ constants if it is set
27 * to a non-zero value, otherwise the default of 3.2-3.4V is used.
