+ * struct ucmb_platform_data - UCMB device descriptor
+ *
+ * @name:              The name of the device. This will also be the name of
+ *                     the misc char device.
+ *
+ * @gpio_cs:           The chipselect GPIO pin. Can be SPI_GPIO_NO_CHIPSELECT.
+ * @gpio_sck:          The clock GPIO pin.
+ * @gpio_miso:         The master-in slave-out GPIO pin.
+ * @gpio_mosi:         The master-out slave-in GPIO pin.
+ *
+ * @mode:              The SPI bus mode. SPI_MODE_*
+ * @max_speed_hz:      The bus speed, in Hz. If zero the speed is not limited.
+ * @msg_delay_ms:      The message delay time, in milliseconds.
+ *                     This is the time the microcontroller takes to process
+ *                     one message.
