[PATCH] lockdep: annotate on-stack completions

2006-07-03T22:27:09+00:00

lockdep needs to have the waitqueue lock initialized for on-stack waitqueues implicitly initialized by DECLARE_COMPLETION(). Annotate on-stack completions accordingly. Has no effect on non-lockdep kernels. Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] SPI: infrastructure to initialize spi_device.mode early

2006-06-28T22:51:01+00:00

This patch adds earlier initialization of spi_device.mode, as needed on boards using nondefault chipselect polarity. An example would be ones using the RS5C348 RTC without an external signal inverter between the RTC chipselect and the SPI controller. Without this mechanism, the first setup() call for that chip would wrongly enable chips, corrupting transfers to/from other chips sharing that SPI bus.

[PATCH] s3c24xx: fix spi driver with CONFIG_PM

Fix compile bug with the S3C24XX SPI driver when CONFIG_PM is set. Signed-off-by: Ben Dooks Cc: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] pxa2xx-spi update

2006-05-21T19:59:20+00:00

Fix some outstanding issues with the pxa2xx_spi driver when running on a PXA270: - Wrong timeout calculation in the setup function due to different peripheral clock rates in the PXAxxx family. - Bad handling of SSSR_TFS interrupts in interrupt_transfer function. - Added locking to interface between the pump_messages workqueue and the pump_transfers tasklet. Much thanks to Juergen Beisert for the extensive testing on the PXA270.

[PATCH] spi: add spi master driver for Freescale MPC83xx SPI controller

2006-05-21T19:59:19+00:00

This driver supports the SPI controller on the MPC83xx SoC devices from Freescale. Note, this driver supports only the simple shift register SPI controller and not the descriptor based CPM or QUICCEngine SPI controller.

[PATCH] minor SPI doc fix

2006-05-21T19:59:19+00:00

Because several developers asked me about referenced but missing spi_add_master(), I think that this patch should be applied ... it corrects comments so they refer to spi_register_master() instead.

[PATCH] SPI: spi_bitbang: clocking fixes

2006-05-16T21:33:58+00:00

This fixes two problems triggered by the MMC stack updating clocks: - SPI masters driver should accept a max clock speed of zero; that's one convention for marking idle devices. (Presumably that helps controllers that don't autogate clocks to "off" when not in use.) - There are more than 1000 nanoseconds per millisecond; setting the clock down to 125 KHz now works properly. Showing once again that Zero (http://en.wikipedia.org/wiki/Zero) is still an inexhaustible number of bugs. Signed-off-by: David Brownell Signed-off-by: Greg Kroah-Hartman
