| 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 | * }; |
