spi: documentation: emphasise spi_master.setup() semantics

2009-04-21T20:41:50+00:00

This is a doc-only patch which I hope will reduce the number of spi_master controller driver patches starting out with a common implementation bug. (As in: almost every spi_master driver I see starts out with its version of this bug. Sigh.) It just re-emphasizes that the setup() method may be called for one device while a transfer is active on another ... which means that most driver implementations shouldn't touch any registers.

Input: ads7846 - introduce platform specific way to synchronize sampling

2009-04-12T00:09:15+00:00

Noises can be introduced when LCD signals are being driven, some platforms provide a signal to assist the synchronization of this sampling procedure. Signed-off-by: Eric Miao Signed-off-by: Andrew Morton Signed-off-by: Dmitry Torokhov

SPI: add dma_alignment field to spi_master

2009-04-07T15:31:07+00:00

Some SPI controllers have restrictions on DMAable buffers alignemt. Currently if the buffer supplied by protocol driver is not properly aligned, the controller silently performs transfer in PIO mode. Addition of dma_alignment field to spi_master allows protocol drivers to perform proper alignment.

spi-gpio: allow operation without CS signal

2009-04-03T02:04:51+00:00

Change spi-gpio so that it is possible to drive SPI communications over GPIO without the need for a chipselect signal. This is useful in very small setups where there's only one slave device on the bus. This patch does not affect existing setups. I use this for a tiny communication channel between an embedded device and a microcontroller. There are not enough GPIOs available for chipselect and it's not needed anyway in this case.

memory_accessor: implement the new memory_accessor interfaces for SPI EEPROMs

2009-04-03T02:04:50+00:00

- Define new setup() hook to export the accessor - Implement accessor methods Moves some error checking out of the sysfs interface code into the layer below it, which is now shared by both sysfs and memory access code.
