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 * };
