Merge tag 'spi-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "A fairly quiet release for the SPI subsystem, the standout changes being: - Core support for implementing bits per word constraints implemented by Stephen Warren, factoring some code out of drivers. - Addition of polling mode support for the s3c64xx driver as some newer Exynos systems have taken the unusual step of removing interrupt support. - Use of the in-IP FIFO and generic dmaengine support for the OMAP2 driver, providing improved performance. - Conversion of the mpc512x driver to use the core message queue infrastructure. The nicest thing being that all the factoring out into common code leads to a negative diffstat overall." * tag 'spi-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (42 commits) spi/s3c64xx: Rely on the compiler eliminating the OF ID table spi: s3c64xx: Added support for exynos5440 spi spi: s3c64xx: Added provision for dedicated cs pin spi: omap2-mcspi: add generic DMA request support to the DT binding spi: omap2-mcspi: convert to dma_request_slave_channel_compat() spi/s3c64xx: Make wait_for_timeout() function name less generic spi: s3c64xx: added support for polling mode spi: omap2-mcspi: Add FIFO buffer support spi: omap2-mcspi: Move bytes per word calculation to the function spi: spi-xilinx: cleanup a check in xilinx_spi_txrx_bufs() spi: spi-nuc900: Remove redundant platform_set_drvdata() spi: spi-fsl-lib: Make mpc8xxx_spi_work static spi: spi-topcliff-pch: Fix sparse warnings spi: spi-xilinx: Remove redundant platform_set_drvdata() spi: spi-xilinx: Add run run-time endian detection spi: mpc512x: use the SPI subsystem's message queue spi: mpc512x: improve throughput in the RX/TX func spi: mpc512x: minor prep before feature change spi: atmel: convert to dma_request_slave_channel_compat() spi: sirf: avoid uninitialized-use warning ...
