- * 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,
- * },
- * };
