- * For each bitbanged SPI bus, set up a platform_device node with:
- *   - name "spi_gpio"
- *   - id the same as the SPI bus number it implements
- *   - dev.platform data pointing to a struct spi_gpio_platform_data
- *
- * Or, see the driver code for information about speedups that are
- * possible on platforms that support inlined access for GPIOs (no
- * spi_gpio_platform_data is used).
- *
- * Use spi_board_info with these busses in the usual way, being sure
- * that the controller_data being the GPIO used for each device's
- * chipselect:
- *
- *	static struct spi_board_info ... [] = {
- *	...
- *		// this slave uses GPIO 42 for its chipselect
- *		.controller_data = (void *) 42,
- *	...
- *		// this one uses GPIO 86 for its chipselect
- *		.controller_data = (void *) 86,
- *	...
- *	};
- *
- * If chipselect is not used (there's only one device on the bus), assign
- * SPI_GPIO_NO_CHIPSELECT to the controller_data:
- *		.controller_data = (void *) SPI_GPIO_NO_CHIPSELECT;
- *
- * If the MISO or MOSI pin is not available then it should be set to
- * SPI_GPIO_NO_MISO or SPI_GPIO_NO_MOSI.
- *
- * If the bitbanged bus is later switched to a "native" controller,
- * that platform_device and controller_data should be removed.

-/**
- * struct spi_gpio_platform_data - parameter for bitbanged SPI master
- * @sck: number of the GPIO used for clock output
- * @mosi: number of the GPIO used for Master Output, Slave In (MOSI) data
- * @miso: number of the GPIO used for Master Input, Slave Output (MISO) data
- * @num_chipselect: how many slaves to allow
- *
- * All GPIO signals used with the SPI bus managed through this driver
- * (chipselects, MOSI, MISO, SCK) must be configured as GPIOs, instead
- * of some alternate function.
- *
- * It can be convenient to use this driver with pins that have alternate
- * functions associated with a "native" SPI controller if a driver for that
- * controller is not available, or is missing important functionality.
- *
- * On platforms which can do so, configure MISO with a weak pullup unless
- * there's an external pullup on that signal.  That saves power by avoiding
- * floating signals.  (A weak pulldown would save power too, but many
- * drivers expect to see all-ones data as the no slave "response".)
