Merge tag 'dmaengine-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine
Pull dmaengine updates from Vinod Koul: "We have couple of drivers removed a new driver and bunch of new device support and few updates to drivers for this round. New drivers/devices: - Intel LGM SoC DMA driver - Actions Semi S500 DMA controller - Renesas r8a779a0 dma controller - Ingenic JZ4760(B) dma controller - Intel KeemBay AxiDMA controller Removed: - Coh901318 dma driver - Zte zx dma driver - Sirfsoc dma driver Updates: - mmp_pdma, mmp_tdma gained module support - imx-sdma become modern and dropped platform data support - dw-axi driver gained slave and cyclic dma support" * tag 'dmaengine-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/vkoul/dmaengine: (58 commits) dmaengine: dw-axi-dmac: remove redundant null check on desc dmaengine: xilinx_dma: Alloc tx descriptors GFP_NOWAIT dmaengine: dw-axi-dmac: Virtually split the linked-list dmaengine: dw-axi-dmac: Set constraint to the Max segment size dmaengine: dw-axi-dmac: Add Intel KeemBay AxiDMA BYTE and HALFWORD registers dmaengine: dw-axi-dmac: Add Intel KeemBay AxiDMA handshake dmaengine: dw-axi-dmac: Add Intel KeemBay AxiDMA support dmaengine: drivers: Kconfig: add HAS_IOMEM dependency to DW_AXI_DMAC dmaengine: dw-axi-dmac: Add Intel KeemBay DMA register fields dt-binding: dma: dw-axi-dmac: Add support for Intel KeemBay AxiDMA dmaengine: dw-axi-dmac: Support burst residue granularity dmaengine: dw-axi-dmac: Support of_dma_controller_register() dmaegine: dw-axi-dmac: Support device_prep_dma_cyclic() dmaengine: dw-axi-dmac: Support device_prep_slave_sg dmaengine: dw-axi-dmac: Add device_config operation dmaengine: dw-axi-dmac: Add device_synchronize() callback dmaengine: dw-axi-dmac: move dma_pool_create() to alloc_chan_resources() dmaengine: dw-axi-dmac: simplify descriptor management dt-bindings: dma: Add YAML schemas for dw-axi-dmac dmaengine: ti: k3-psil: optimize struct psil_endpoint_config for size ...
