Merge tag 'spi-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown: "A fairly quiet release for SPI, nothing really going on in the core although there's been quite a bit of driver related activity. This includes the addition of some shared code in drivers/memory for the Renesas RPC-IF which is used by a newly added SPI driver, the memory subsystem doesn't seem to have a fixed maintainer at the minute and this seemed like the most sensible way to get that hardware supported. - Quite a few cleanups and optimizations for the Altera, Qualcomm GENI, sun6i and lantiq drivers. - Several more GPIO descriptor conversions. - Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi. - New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and R8A774e1" * tag 'spi-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (119 commits) dt-bindings: lpspi: New property in document DT bindings for LPSPI spi: lpspi: fix using CS discontinuously on i.MX8DXLEVK spi: lpspi: remove unused fsl_lpspi->chipselect spi: lpspi: Fix kernel warning dump when probe fail after calling spi_register spi: rockchip: Fix error in SPI slave pio read spi: rockchip: Support 64-location deep FIFOs spi: rockchip: Config spi rx dma burst size depend on xfer length spi: spi-topcliff-pch: drop call to wakeup-disable spi: spidev: Align buffers for DMA spi: correct kernel-doc inconsistency spi: sun4i: update max transfer size reported spi: imx: enable runtime pm support spi: update bindings for MT8192 SoC spi: mediatek: add spi support for mt8192 IC spi: Add bindings for Lightning Mountain SoC spi: lantiq: Add support to Lightning Mountain SoC spi: lantiq: Move interrupt configuration to SoC specific data structure spi: lantiq: Add fifo size bit mask in SoC specific data structure spi: lantiq: Add support to acknowledge interrupt spi: lantiq: Move interrupt control register offesets to SoC specific data structure ...
