+ * 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,
+ * },
+ * };
