documentation: move spidev_fdx example to its own source file

2008-04-28T15:58:31+00:00

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/.)

spi: documentation tweaks

2008-04-09T01:25:53+00:00

Update SPI documentation to clarify some areas of recent confusion: clock
polarity takes effect when chipselect goes active; and zero length buffers are
OK in certain cases.

Convert files to UTF-8 and some cleanups

2007-10-19T21:21:04+00:00

* Convert files to UTF-8.

  * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

  * Correct town names (Goettingen -> Göttingen)

  * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

spi doesn't need class_device

2007-10-16T16:43:10+00:00

Make the SPI framework and drivers stop using class_device.  Update docs
accordingly ...  highlighting just which sysfs paths should be
"safe"/stable.

spidev_test utility

2007-07-31T22:39:40+00:00

This is a simple utility used to test SPI functionality.  It could stand
growing options to support using other test data patterns; this initial
version only issues full duplex transfers, which rules out 3WIRE or
Microwire links.

spi_lm70llp parport adapter driver

2007-07-17T17:23:04+00:00

This adds a driver for the LM70-LLP parport adapter, which is an eval board
for the LM70 temperature sensor.  For those without that board, it may be a
simpler example of a parport-to-SPI adapter then spi_butterfly.

spi doc update: describe clock mode bits

2007-05-24T03:14:11+00:00

Update the SPI documentation to cover a few points that have proven to be
confusing or unclear; most notably the two clock mode bits.

SPI kerneldoc

2007-05-08T18:15:16+00:00

Various documentation updates for the SPI infrastructure, to clarify things
that may not have been clear, to cope with lack of editing, and fix
omissions.

Also, plug SPI into the kernel-api DocBook template, and fix all the
resulting glitches in document generation.

/dev/spidevB.C interface

2007-05-08T18:15:15+00:00

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.
