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  * };
