spi: spidev: Add support for Dual/Quad SPI Transfers

2014-02-27T04:51:29Z

Add support for Dual/Quad SPI Transfers to the spidev API. As this uses SPI mode bits that don't fit in a single byte, two new ioctls (SPI_IOC_RD_MODE32 and SPI_IOC_WR_MODE32) are introduced. Signed-off-by: Geert Uytterhoeven Signed-off-by: Mark Brown

documentation: move spidev_fdx example to its own source file

2008-04-28T15:58:31Z

Move sample source code to its own source file so that it can be used easier and build-tested/check/maintained by anyone. (Makefile changes are in a separate patch for all of Documentation/.)

/dev/spidevB.C interface

2007-05-08T18:15:15Z

Add a filesystem API for stack. The initial version of this interface is purely synchronous. dbrownell@users.sourceforge.net: Cleaned up, bugfixed; much simplified; added preliminary documentation. Works with mdev given CONFIG_SYSFS_DEPRECATED; and presumably udev. Updated SPI_IOC_MESSAGE ioctl to full spi_message semantics, supporting groups of one or more transfers (each of which may be full duplex if desired). This is marked as EXPERIMENTAL with an explicit disclaimer that the API (notably the ioctls) is subject to change.
