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 | * }; | |
