  17 * struct plat_max3100 - MAX3100 SPI UART platform data
  18 * @loopback:            force MAX3100 in loopback
  19 * @crystal:             1 for 3.6864 Mhz, 0 for 1.8432
  20 * @max3100_hw_suspend:  MAX3100 has a shutdown pin. This is a hook
  21 *                       called on suspend and resume to activate it.
  22 * @poll_time:           poll time for CTS signal in ms, 0 disables (so no hw
  23 *                       flow ctrl is possible but you have less CPU usage)
  24 *
  25 * You should use this structure in your machine description to specify
  26 * how the MAX3100 is connected. Example:
  27 *
  28 * static struct plat_max3100 max3100_plat_data = {
  29 *  .loopback = 0,
  30 *  .crystal = 0,
  31 *  .poll_time = 100,
  32 * };
  33 *
  34 * static struct spi_board_info spi_board_info[] = {
  35 * {
  36 *  .modalias   = "max3100",
  37 *  .platform_data      = &max3100_plat_data,
  38 *  .irq                = IRQ_EINT12,
  39 *  .max_speed_hz       = 5*1000*1000,
  40 *  .chip_select        = 0,
  41 * },
  42 * };
