  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  * };
