spi_txx9 controller driver

2007-07-17T17:23:05+00:00

This is a driver for SPI controller built into TXx9 MIPS SoCs.
This driver is derived from arch/mips/tx4938/toshiba_rbtx4938/spi_txx9.c.

SPI: omap2_mcspi driver

2007-07-17T17:23:05+00:00

Add OMAP24XX McSPI (Multichannel SPI) controller driver.  This driver is
tested very well under OMAP GIT tree with N800 - Nokia Internet Tablet, and
some other OMAP2 boards.

Recent updates included bugfixes, cleanups, speedups, and better
conformance to the current SPI programming interface.  This doesn't yet
understand the third controller instance on the OMAP 2430.

[david-b@pacbell.net: more minor cleanups to the omap2_mcspi driver]

SPI: tle620x power switch driver

2007-07-17T17:23:05+00:00

Add support for the Infineon TLE62x0 series of low-side driver chips, such
as the TLE6220 or TLE6230.  These can be viewed as output GPIOs specialized
for power switching applications.  The driver provides a userspace
interface to those GPIOs, and to the switch status they provide.

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.

au1550 SPI controller driver

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

Here is a driver for the Alchemy au1550 PSC (Programmable Serial
Controller) in SPI master mode.

It supports dma transfers using the Alchemy descriptor based dma controller
for 4-8 bits per word SPI transfers.  For 9-24 bits per word transfers, pio
irq based mode is used to avoid setup of dma channels from scratch on each
number of bits per word change.

Tested with au1550; this may also work on other MIPS Alchemy cpus, like
au1200/au1210/au1250.  Used extensively with SD card connected via SPI;
this handles 8.1MHz SPI clock transfers using dma without any problem (the
highest SPI clock freq possible with au1550 running on 324MHz).

The driver supports sharing of SPI bus by multiple devices.  All features
of Alchemy SPI mode are supported (all SPI modes, msb/lsb first, bits per
word in 4-24 range).

As the SPI clock of the controller depends on main input clock that shall
be configured externally, platform data structure for au1550 SPI controller
driver contains mainclk_hz attribute to define the input clock rate.  From
this value, dividers of the controller for SPI clock are set up for
required frequency.

Whitespace and section fixups.  Remove partial workaround for platform
setup bug in dma_mask setup; it couldn't work with multiple controllers.

/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.

[PATCH] SPI: atmel_spi driver

2007-02-14T16:09:53+00:00

Driver for the Atmel on-chip SPI master controller.

Tested primarily on AVR32/AT32AP7000/ATSTK1000 using mtd_dataflash and the
jffs2 filesystem.  Should also work fine on various AT91 ARM-based chips
like AT91SAM926x and AT91RM9200.

Hardware documentation can be found in the AT32AP7000 data sheet, or its
AT91 siblings, which can be downloaded from
