/**
* 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,
* },
* };
