Hi, the main goal of the patchset is to support SPI cnnected device without CS line link. The first two patches make the s3c64xx driver to consider the case of a disconnected CS line. This is done by adding a property in the DTS ("no-cs-readback") which informs the device driver the absence of a chip selection link. The last three patches are just some code re-work and beautification. Changelog: V1 -> V2 - the first version of the patchset was removing an 'if' statement on "!spi->chip_select" which was causing the SPI core to fail. In this case the drivers would have been able to set a chip_select = 0 in absence of a CS link. After a short discussion with Mark, this has been replaced, as described above, by a property in the DTS. - one more patch has been added which assigns to some variable the proper type - some typos fixed in the commit messages Thanks, Andi Andi Shyti (5): spi: s3c64xx: group the CS signalling writes in a single function spi: s3c64xx: consider the case when the CS line is not connected spi: s3c64xx: do not configure the device twice spi: s3c64xx: simplify if statement in prepare_transfer function spi: s3c64xx: use unsigned type for fifo handling variables .../devicetree/bindings/spi/spi-samsung.txt | 3 + drivers/spi/spi-s3c64xx.c | 114 +++++++++++---------- include/linux/platform_data/spi-s3c64xx.h | 1 + 3 files changed, 65 insertions(+), 53 deletions(-) -- 2.8.1 -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
