Merge tag 'spi-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "As well as the usual driver updates and cleanups there's a few improvements to the core here: - The start of some improvements to factor out more of the SPI message loop into the core. Right now this is just simplifying the code a bit but hopefully next time around we'll also have managed to roll out some noticable performance improvements which drivers can take advantage of. - Support for loading modules for ACPI enumerated SPI devices. - Managed registration for SPI controllers. - Helper for another common I/O pattern" * tag 'spi-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (116 commits) spi/hspi: add device tree support spi: atmel: fix return value check in atmel_spi_probe() spi: spi-imx: only enable the clocks when we start to transfer a message spi/s3c64xx: Fix doubled clock disable on suspend spi/s3c64xx: Do not ignore return value of spi_master_resume/suspend spi: spi-mxs: Use u32 instead of uint32_t spi: spi-mxs: Don't set clock for each xfer spi: spi-mxs: Clean up setup_transfer function spi: spi-mxs: Remove check of spi mode bits spi: spi-mxs: Fix race in setup method spi: spi-mxs: Remove bogus setting of ssp clk rate field spi: spi-mxs: Remove full duplex check, spi core already does it spi: spi-mxs: Fix chip select control bits in DMA mode spi: spi-mxs: Fix extra CS pulses and read mode in multi-transfer messages spi: spi-mxs: Change flag arguments in txrx functions to bit flags spi: spi-mxs: Always clear INGORE_CRC, to keep CS asserted spi: spi-mxs: Remove mxs_spi_enable and mxs_spi_disable spi: spi-mxs: Always set LOCK_CS spi/s3c64xx: Add missing pm_runtime_put on setup fail spi/s3c64xx: Add missing pm_runtime_set_active() call in probe() ...
