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