2013-07-11spi: revert master->setup function removal for altera and nuc900Stephen Warren
Commit 24778be "spi: convert drivers to use bits_per_word_mask" removed what appeared to be redundant code from many drivers. However, it appears that in the spi-bitbang case, these functions are required by the spi-bitbang core, even if they don't do anything. Restore them. For 3.12, the spi-bitbang core should be adjusted not to require these callbacks to exist if they don't need to do anything. This is the equivalent of Michal Simek's patch "spi/xilinx: Revert master->setup function removal", applied to other affected drivers.

2013-06-26spi/s3c64xx: Rely on the compiler eliminating the OF ID tableMark Brown
This should work with modern compilers, isn't that much of an issue if it goes wrong and it ensures that the DT-only hardware variants don't leave unreferenced parameters structures lying around. Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-25spi: s3c64xx: Added support for exynos5440 spiGirish K S
This patch adds support for the exynos5440 spi controller. The integration of the spi IP in exynos5440 is different from other SoC's. The I/O pins are no more configured via gpio, they have dedicated pins. Signed-off-by: Girish K S <ks.giri@samsung.com> Signed-off-by: Mark Brown <broonie@linaro.org>
2013-06-25spi: s3c64xx: Added provision for dedicated cs pinGirish K S
The existing driver supports gpio based /cs signal. For controller's that have one device per controller, the slave device's /cs signal might be internally controlled by the chip select bit of slave select register. They are not externally asserted/deasserted using gpio pin. This patch adds support for controllers with dedicated /cs pin. if "cs-gpio" property doesnt exist in a spi dts node, the controller would treat the /cs pin as dedicated.

2013-06-24spi: omap2-mcspi: convert to dma_request_slave_channel_compat()Matt Porter
Convert dmaengine channel requests to use dma_request_slave_channel_compat(). This supports the DT case of platforms requiring channel selection from either the OMAP DMA or the EDMA engine. AM33xx only boots from DT and is the only user implementing EDMA so in the !DT case we can default to the OMAP DMA filter.
