spi_gpio driver

2009-01-06T23:59:19Z

Generalize the old at91rm9200 "bootstrap" bitbanging SPI master driver as "spi_gpio", so it works with arbitrary GPIOs and can be configured through platform_data. Such SPI masters support: - any number of bus instances (bus_num is the platform_device.id) - any number of chipselects (one GPIO per spi_device) - all four SPI_MODE values, and SPI_CS_HIGH - i/o word sizes from 1 to 32 bits; - devices configured as with any other spi_master controller When configured using platform_data, this provides relatively low clock rates. On platforms that support inlined GPIO calls, significantly improved transfer speeds are also possible with a semi-custom driver. (It's still painful when accessing flash memory, but less so.) Sanity checked by using this version to replace both native controllers on a board with six different SPI slaves, relying on three different SPI_MODE_* values and both SPI_CS_HIGH settings for correct operation.

spi: new orion_spi driver

2008-08-05T21:33:46Z

This adds an SPI driver for the SPI controller found in various Marvell Orion ARM SoCs. It currently supports only one slave, which must use SPI mode 0.

spi: SuperH SPI using SCI

2008-02-06T18:41:11Z

Add support for SPI over SCI pins. SCI is a very simple serial controller block that can be found on older SuperH processors. In theory it is possible to use the SCI hardware block in syncronous mode, but this version of the driver simply hooks up the bit banging code on the SCI pins.

spi_txx9 controller driver

2007-07-17T17:23:05Z

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. Signed-off-by: Atsushi Nemoto Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

SPI: omap2_mcspi driver

2007-07-17T17:23:05Z

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.

SPI master driver for Xilinx virtex

SPI: tle620x power switch driver

2007-07-17T17:23:05Z

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

2007-07-17T17:23:04Z

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. Signed-off-by: Kaiwan N Billimoria Doc, coding style, and interface updates; build fixes.
