+ * 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,
+ * },
+ * };
