| /** |
| * struct plat_max3100 - MAX3100 SPI UART platform data |
| * @loopback: force MAX3100 in loopback |
| * @crystal: 1 for 3.6864 Mhz, 0 for 1.8432 |
| * @max3100_hw_suspend: MAX3100 has a shutdown pin. This is a hook |
| * called on suspend and resume to activate it. |
| * @poll_time: poll time for CTS signal in ms, 0 disables (so no hw |
| * flow ctrl is possible but you have less CPU usage) |
| * |
| * You should use this structure in your machine description to specify |
| * how the MAX3100 is connected. Example: |
| * |
| * static struct plat_max3100 max3100_plat_data = { |
| * .loopback = 0, |
| * .crystal = 0, |
| * .poll_time = 100, |
| * }; |
| * |
| * static struct spi_board_info spi_board_info[] = { |
| * { |
| * .modalias = "max3100", |
| * .platform_data = &max3100_plat_data, |
| * .irq = IRQ_EINT12, |
| * .max_speed_hz = 5*1000*1000, |
| * .chip_select = 0, |
| * }, |
| * }; |
