17 * struct plat_max3100 - MAX3100 SPI UART platform data
18 * @loopback: force MAX3100 in loopback
19 * @crystal: 1 for 3.6864 Mhz, 0 for 1.8432
20 * @max3100_hw_suspend: MAX3100 has a shutdown pin. This is a hook
21 * called on suspend and resume to activate it.
22 * @poll_time: poll time for CTS signal in ms, 0 disables (so no hw
23 * flow ctrl is possible but you have less CPU usage)
24 *
25 * You should use this structure in your machine description to specify
26 * how the MAX3100 is connected. Example:
27 *
28 * static struct plat_max3100 max3100_plat_data = {
29 * .loopback = 0,
30 * .crystal = 0,
31 * .poll_time = 100,
32 * };
33 *
34 * static struct spi_board_info spi_board_info[] = {
35 * {
36 * .modalias = "max3100",
37 * .platform_data = &max3100_plat_data,
38 * .irq = IRQ_EINT12,
39 * .max_speed_hz = 5*1000*1000,
40 * .chip_select = 0,
41 * },
42 * };
