Merge tag 'spi-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "A quiet release for SPI, not even many driver updates: - Add a dummy loopback driver for use in exercising framework features during development. - Move the test utilities to tools/ and add support for transferring data to and from a file instead of stdin and stdout to spidev_test. - Support for Mediatek MT2701 and Renesas AG5 deices" * tag 'spi-v4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (69 commits) spi: loopback: fix typo in MODULE_PARM_DESC spi: sun4i: Prevent chip-select from being activated twice before a transfer spi: loopback-test: spi_check_rx_ranges can get always done spi: loopback-test: rename method spi_test_fill_tx to spi_test_fill_pattern spi: loopback-test: write rx pattern also when running without tx_buf spi: fsl-espi: expose maximum transfer size limit spi: expose master transfer size limitation. spi: zynq: use to_platform_device() spi: cadence: use to_platform_device() spi: mediatek: Add spi support for mt2701 IC spi: mediatek: merge all identical compat to mtk_common_compat spi: mtk: Add bindings for mediatek MT2701 soc platform spi: mediatek: Prevent overflows in FIFO transfers spi: s3c64xx: Remove unused platform_device_id entries spi: use to_spi_device spi: dw: Use SPI_TMOD_TR rather than magic const 0 to set tmode spi: imx: defer spi initialization, if DMA engine is spi: imx: return error from dma channel request spi: imx: enable loopback only for ECSPI controller family spi: imx: fix loopback mode setup after controller reset ...
