Merge tag 'spi-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "With the exception of some refactoring to fix long standing issues where we weren't handling cache syncs properly for messages which had PIO and DMA transfers going to the same page correctly there has been no work on the core this time around, and it's also been quite a quiet release for the drivers too: - Fix cache syncs for cases where we have DMA and PIO transfers in the same message going to the same page - Update the fsl_spi driver to use transfer_one() rather than a custom transfer function - Support for configuring transfer speeds with the AMD SPI controller - Support for a second chip select and 64K erase on Intel SPI - Support for Microchip coreQSPI, Nuvoton NPCM845, NXP i.MX93, and Rockchip RK3128 and RK3588" * tag 'spi-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (73 commits) spi: Ensure that sg_table won't be used after being freed spi: spi-gxp: Use devm_platform_ioremap_resource() spi: s3c64xx: Fix large transfers with DMA spi: Split transfers larger than max size spi: Fix cache corruption due to DMA/PIO overlap spi: Save current RX and TX DMA devices spi: mt65xx: Add dma max segment size declaration spi: migrate mt7621 text bindings to YAML spi: renesas,sh-msiof: Add r8a779g0 support spi: spi-fsl-qspi: Use devm_platform_ioremap_resource_byname() spi: spi-fsl-lpspi: Use devm_platform_get_and_ioremap_resource() spi: spi-fsl-dspi: Use devm_platform_get_and_ioremap_resource() spi/omap100k:Fix PM disable depth imbalance in omap1_spi100k_probe spi: dw: Fix PM disable depth imbalance in dw_spi_bt1_probe spi: cadence-quadspi: Fix PM disable depth imbalance in cqspi_probe spi: s3c24xx: Switch to use devm_spi_alloc_master() spi: xilinx: Switch to use devm_spi_alloc_master() spi: img-spfi: using pm_runtime_resume_and_get instead of pm_runtime_get_sync spi: aspeed: Remove redundant dev_err call spi: spi-mpc52xx: switch to using gpiod API ...
