  /**
   * 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,
   * },
   * };
