spi: Move spi code from Documentation to tools

2015-11-23T14:54:01+00:00

Jon Corbet requested this code moved with the last changeset, https://lkml.org/lkml/2015/3/1/144, but the patch was not applied because it missed the Makefile. Moved spidev_test, spidev_fdx and their Makefile infrastructure. Signed-off-by: Joshua Clayton Signed-off-by: Mark Brown

spi: spidev_test gives error upon 1-byte transfer

2010-04-29T22:40:30+00:00

The sample application spidev_test.c is using SPI_IOC_MESSAGE ioctl to do an SPI transfer. This ioctl returns the number of bytes successfully transmitted or a negative error code upon erroneous completion. The application however is returning an error if the result of the ioclt if the return value is 1. This makes the application to fail upon 1-byte length transfers.

spi: new spi->mode bits

2009-07-01T01:56:00+00:00

Add two new spi_device.mode bits to accomodate more protocol options, and pass them through to usermode drivers: * SPI_NO_CS ... a second 3-wire variant, where the chipselect line is removed instead of a data line; transfers are still full duplex. This obviously has STRONG protocol implications since the chipselect transitions can't be used to synchronize state transitions with the SPI master. * SPI_READY ... defines open drain signal that's pulled low to pause the clock. This defines a 5-wire variant (normal 4-wire SPI plus READY) and two 4-wire variants (READY plus each of the 3-wire flavors). Such hardware flow control can be a big win. There are ADC converters and flash chips that expose READY signals, but not many host controllers support it today. The spi_bitbang code should be changed to use SPI_NO_CS instead of its current nonportable hack. That's a mode most hardware can easily support (unlike SPI_READY).
