Merge tag 'spi-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "Lots of stuff going on in the core for SPI this time around, the two big changes both being around time in different forms: - A rework of delay times from Alexandru Ardelean which makes the ways in which they are specified more consistent between drivers so that what's available to clients is less dependent on the hardware implementation. - Support for PTP timestamping of transfers from Vladimir Oltean, useful for use with precision clocks with SPI control interfaces. - Big cleanups for the Atmel, PXA2xx and Zynq QSPI drivers" * tag 'spi-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (119 commits) dt-bindings: spi: Convert stm32 QSPI bindings to json-schema spi: pic32: Retire dma_request_slave_channel_compat() spi: Fix Kconfig indentation spi: mediatek: add SPI_CS_HIGH support spi: st-ssc4: add missed pm_runtime_disable spi: tegra20-slink: add missed clk_unprepare spi: tegra20-slink: Use dma_request_chan() directly for channel request spi: tegra114: Use dma_request_chan() directly for channel request spi: s3c64xx: Use dma_request_chan() directly for channel request spi: qup: Use dma_request_chan() directly for channel request spi: pl022: Use dma_request_chan() directly for channel request spi: imx: Use dma_request_chan() directly for channel request spi: fsl-lpspi: Use dma_request_chan() directly for channel request spi: atmel: Use dma_request_chan() directly for channel request spi: at91-usart: Use dma_request_chan() directly for channel request spi: fsl-cpm: Correct the free:ing spi: Fix regression to return zero on success instead of positive value spi: pxa2xx: Add missed security checks spi: nxp-fspi: Use devm API to fix missed unregistration of controller spi: omap2-mcspi: Remove redundant checks ...
