Blackfin SPI driver: fix bug SPI DMA incomplete transmission

2007-06-11T09:34:17+00:00

SPI writes intermittently drop bytes at end of DMA transfer http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=3205 http://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_item_id=2892 Signed-off-by: Mike Frysinger Signed-off-by: Bryan Wu

SPI dynamic busid generation bugfix

2007-06-04T20:25:09+00:00

Fix SPI dynamic bus ID assignment to start at 2^15-1 rather than a negative number. Valid bus ids are supposed to be positive, and are (now) stored in an 's16' value. Signed-off-by: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

SPI: Freescale iMX SPI controller driver fixes

2007-06-01T15:18:30+00:00

Fix 2 bugs: - SPI_DMA_RHDMA bad value. - Missing return value in setup() function (lost passing from patch-2.6.20-rc4-spi_imx to patch-2.6.20-rc6-spi_imx). Signed-off-by: Andrea Paterniani Cc: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

atmel_spi dma address bugfix

2007-06-01T15:18:29+00:00

When either rx_buf or tx_buf is not being used, i.e. for plain read- or write operations, the atmel_spi uses a fixed-size DMA buffer instead. If the transfer is longer than the size of this buffer, it is split into multiple DMA transfers. When the transfer is split like this, the atmel_spi driver ends up using the same DMA address again and again even for the buffer that came from the user, which is of course wrong. Fix this by adding the number of bytes already transferred to the DMA address so that the data ends up in the right place. Thanks to Wu Xuan for discovering this bug.

omap_uwire: SPI_CPHA mode bugfix

2007-05-24T03:14:15+00:00

The omap_uwire controller driver handles SPI_CPHA incorrectly; It should mean: CPHA=0 ... sample at leading edge of clock CPHA=1 ... sample at trailing edge of clock This bug has been masked by inverse bugs in layered drivers; and was uncovered by running some of them on non-OMAP hardware.

spi: potential memleak in spidev_ioctl

spi/spidev: check message size before copying

2007-05-24T03:14:12+00:00

Message size needs to be checked before copying, or bad things could happen. Signed-off-by: Domen Puncer Signed-off-by: David Brownell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mpc52xx_psc_spi: fix it for CONFIG_PPC_MERGE

2007-05-24T03:14:11+00:00

Fix mpc5200 PSC SPI driver to actually work for CONFIG_PPC_MERGE - s/mpc52xx/mpc5200/, as this was changed in device tree some time ago - fix spi id detection The move from 'ppc' to 'powerpc' didn't quite match the latest kernel.org code.

Blackfin SPI: cleanup according to David Brownell's review

2007-05-21T16:50:24+00:00

a) platorm_driver_probe(...) instead of platform_driver_register(&driver); b) set bfin_spi_enable and bfin_spi_disable static c) Why is the width flag a u32? d) maybe use dev_dbg() instead of pr_debug() Signed-off-by: Bryan Wu Signed-off-by: Linus Torvalds
