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 * };
