   9  * @name:               The name of the device. This will also be the name of
  10  *                      the misc char device.
  11  *
  12  * @gpio_cs:            The chipselect GPIO pin. Can be SPI_GPIO_NO_CHIPSELECT.
  13  * @gpio_sck:           The clock GPIO pin.
  14  * @gpio_miso:          The master-in slave-out GPIO pin.
  15  * @gpio_mosi:          The master-out slave-in GPIO pin.
  16  *
  17  * @mode:               The SPI bus mode. SPI_MODE_*
  18  * @max_speed_hz:       The bus speed, in Hz. If zero the speed is not limited.
  19  * @msg_delay_ms:       The message delay time, in milliseconds.
  20  *                      This is the time the microcontroller takes to process
  21  *                      one message.
