/** |
|
* 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, |
|
* }, |
|
* }; |
