Merge tag 'spi-for-linus' of git://git.secretlab.ca/git/linux
Pull SPI changes from Grant Likely: "Changes to both core spi code and spi device drivers. The driver changes are the usual set of bug fixes and platform enablement. Core code changes include: - More intelligent assignment of SPI bus numbers when using DT - Common mechanism for using gpios as CS lines - Pull checks for bits_per_word and transfer speed out of drivers and into core code - Ensure temporary DMA buffers are DMA safe" * tag 'spi-for-linus' of git://git.secretlab.ca/git/linux: (50 commits) spi: Document cs_gpios and cs_gpio in kernel-doc spi/of: Fix initialization of cs_gpios array spi/pxa2xx: add support for Lynxpoint SPI controllers spi/pxa2xx: add support for Intel Low Power Subsystem SPI spi/pxa2xx: add support for SPI_LOOP spi/pxa2xx: add support for runtime PM spi/pxa2xx: add support for DMA engine spi/pxa2xx: break out the private DMA API usage into a separate file spi/ath79: add shutdown handler spi/mips-lantiq: set SPI_MASTER_HALF_DUPLEX flag spi/mips-lantiq: make use of spi_finalize_current_message spi/bcm63xx: work around inability to keep CS up spi/davinci: use request_threaded_irq() to fix deadlock spi/orion: Use module_platform_driver() spi/bcm63xx: reject transfers unable to transfer spi: Ensure memory used for spi_write_then_read() is DMA safe spi/spi-mpc512x-psc: init mode bits supported by the driver spi/mpc512x-psc: don't use obsolet cell-index property spi: Remove erroneous __init, __exit and __exit_p() references in drivers spi/s3c64xx: fix checkpatch warnings and error ...
