spi: new orion_spi driver

2008-08-05T21:33:46+00:00

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 Kconfig simplifications

2008-07-24T17:47:30+00:00

Use "if SPI_MASTER" to remove numerous dependencies.

[dbrownell@users.sourceforge.net: remove a couple now-needless EXPERIMENTAL dependencies too]

spi_mpc83xx: much improved driver

2008-05-13T15:02:25+00:00

The current driver may cause glitches on SPI CLK line since one must disable
the SPI controller before changing any HW settings.  Fix this by implementing
a local spi_transfer function that won't change speed and/or word size while
CS is active.

While doing that heavy lifting a few other issues were addressed too:
 - Make word size 16 and 32 work too.
 - Honor bits_per_word and speed_hz in spi transaction.
 - Optimize the common path.

This also stops using the "bitbang" framework (except for a few constants).

spi: SuperH SPI using SCI

2008-02-06T18:41:11+00:00

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.

[ARM] pxa: make pxa2xx_spi driver use ssp_request()/ssp_free()

2008-01-26T15:07:52+00:00

1. make pxa2xx_spi.c use ssp_request() and ssp_free() to get the common
   information of the designated SSP port.

2. remove those IRQ/memory request code, ssp_request() has done that for
   the driver

3. the SPI platform device is thus made psuedo, no resource (memory/IRQ)
   has to be defined, all will be retreived by ssp_request()

4. introduce ssp_get_clk_div() to handle controller difference in clock
   divisor setting

5. use clk_xxx() API for clock enable/disable, and clk_get_rate() to
   handle the different SSP clock frequency between different processors

spi_mpc83xx handles other processors with QUICC engine

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

Currently, all QE SPI controllers are almost the same comparing to
MPC83xx's, thus let's use that driver for them.

Tested to work on MPC85xx in loopback mode.

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.
