5 | * struct s3c24xx_mci_pdata - sd/mmc controller platform data | ||
6 | * @no_wprotect: Set this to indicate there is no write-protect switch. | ||
7 | * @no_detect: Set this if there is no detect switch. | ||
8 | * @wprotect_invert: Invert the default sense of the write protect switch. | ||
9 | * @detect_invert: Invert the default sense of the write protect switch. | ||
10 | * @use_dma: Set to allow the use of DMA. | ||
11 | * @gpio_detect: GPIO number for the card detect line. | ||
12 | * @gpio_wprotect: GPIO number for the write protect line. | ||
13 | * @ocr_avail: The mask of the available power states, non-zero to use. | ||
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. | ||
