Merge tag 'spi-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "A few core tweaks this time together with the usual collection of driver specific updates and fixes plus a larger than average selection of new device support: - fix DMA mapping of unaligned vmalloc() buffers - statistics tracking transfer volumes exposed via sysfs - new drivers for Freescale MPC5125, Intel Sunrise Point, Mediatek SoCs, and Netlogic XLP SoCs" * tag 'spi-v4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (66 commits) spi: sh-msiof: Fix FIFO size to 64 word from 256 word spi: fsl-(e)spi: Fix checking return value of devm_ioremap_resource spi: Add DT bindings documentation for Netlogic XLP SPI controller spi/xlp: SPI controller driver for Netlogic XLP SoCs spi: fsl-espi: add runtime PM spi: fsl-(e)spi: simplify cleanup code spi: fsl-(e)spi: migrate to using devm_ functions to simplify cleanup spi: mediatek: fix SPI_CMD_PAUSE_IE macro error spi: check bits_per_word in spi_setup spi: mediatek: replace *_time name spi: mediatek: add PM clk_prepare_enable fail flow spi: mediatek: replace int with u32, delete TAB and define MTK_SPI_PAUSE_INT_STATUS marco spi: mediatek: add linux/io.h include file spi/bcm63xx-hsspi: add support for dual spi read/write spi: dw: Allow interface drivers to limit data I/O to word sizes dt: snps,dw-apb-ssi: Document new I/O data register width property spi: Fall back to master maximum speed if no slave speed specified spi: mediatek: use BIT() to instead of SPI_CMD_*_OFFSET spi: medaitek: revise quirks compatibility style spi: mediatek: fix spi incorrect endian usage ...
