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. Signed-off-by: Tony Jones Signed-off-by: David Brownell Cc: Greg KH Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[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.

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.

spi kerneldoc update

This adds kerneldoc to the SPI framework. The "spi_driver" and "spi_board_info" structs were previously not described. Signed-off-by: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

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

Loopback mode is supported by various controllers. This mode can be useful for testing, especially in conjunction with spidev driver. Signed-off-by: Anton Vorontsov Signed-off-by: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Input: ads7846 - re-check pendown status before reporting events

2007-07-18T04:36:04+00:00

Pendown status from the PENIRQ pin is currently read only at the beginning of a sample set. If the pen is lifted just after sampling has began then sampled values become wrong. This patch adds an optional platform penirq_recheck_delay attribute. If non-zero, samples are only reported to the input subsystem if PENIRQ is still active that long after the samples taken.

Input: ads7846 - introduce sample settling delay

2007-07-18T04:35:56+00:00

The ads7846 driver has support for filtering, but when the chip gets deselected between samples this causes noise. This patch adds support for an optional settling delay time, so that two consecutive samples will be taken with the specified delay time apart. This ensures that the chip won't be deselected, so the noise won't appear. Filtering can still be done, but will have less work to do since each time a new sample is taken the same delay applies.
