mmc_spi: mmc_spi.h should include linux/interrupts.h

2008-06-02T22:27:10+00:00

Since mmc_spi.h uses irqreturn_t type, it should include appropriate
header, otherwise build will break if users didn't include it (some of
them do not use interrupts).

Input: ads7846 - simplify support of external vREF (and ads7843)

2008-04-02T04:43:01+00:00

This updates the ads7846 driver to handle external vREF (required
on boards using ads7843 chips) without module parameters, and also
removes a needless variable with its associated bogus gcc warning.

spi doesn't need class_device

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

Make the SPI framework and drivers stop using class_device.  Update docs
accordingly ...  highlighting just which sysfs paths should be
"safe"/stable.

[ALSA] ALSA sound driver for the AT73C213 DAC using Atmel SSC driver

2007-10-16T13:57:50+00:00

This patch adds support for the AT73C213 DAC using the misc Atmel SSC driver in
I2S mode. The driver also requires a SPI to setup the registers and control
volume.
It has been tested with an AT32AP7000 on the ATSTK1000 development board. The
driver should also work with any Atmel device with an SSC module supported by
the Atmel SSC driver (atmel-ssc).
The atmel-ssc driver is just submitted to the Linux kernel. Please see mail
thread http://lkml.org/lkml/2007/7/16/32

mmc_spi host driver

2007-09-23T20:17:27+00:00

This is the latest version of the MMC-over-SPI support.  It works
on 2.6.23-rc2 plus git-mmc (from rc1-mm2), along with the preceding
patches which teach the rest of the MMC stack about SPI.

The main issue of note is that sometimes cards need to be power cycled
to recover after certain faults.  Also, it may sometimes be necessary
to disable CRCs.  ("modprobe mmc_core use_spi_crc=n")

spidev supports more communications modes

2007-07-31T22:39:40+00:00

The spidev driver doesn't currently expose all SPI communications modes to
userspace.  This passes them all through to the driver.

Two of them are potentially troublesome, in the sense that they could cause
hardware conflicts on shared busses.  It might be appropriate to add some
privilege checks for for those modes.

SPI loopback mode definition

2007-07-31T22:39:40+00:00

Loopback mode is supported by various controllers.  This mode can be
useful for testing, especially in conjunction with spidev driver.
