+ * @pin_miso: The GPIO pin number of the MISO pin.
+ *
+ * @pin_mosi: The GPIO pin number of the MOSI pin.

+ * @pin_cs: The GPIO pin number of the CHIPSELECT pin.

+ * @cs_activelow: If true, the chip is selected when the CS line is low.
+ *
+ * @no_spi_delay: If true, no delay is done in the lowlevel bitbanging.
+ *                Note that doing no delay is not standards compliant,

+ *                   device is registered.
+ * @boardinfo_setup_data: Data argument passed to boardinfo_setup().
