The eDMA v3 brings alterations in the register layout, particularly, the separation of channel control registers into different channels. The Transfer Control Descriptor (TCD) layout, however, remains identical with only the offset being changed. The first ten patches aim at tidying up the existing Freescale eDMA code and laying the groundwork for the integration of eDMA v3 support. Patch 1-10: These patches primarily focus on cleaning up and refactoring the existing fsl_edma driver code. This is to accommodate the upcoming changes and new features introduced with the eDMA v3. Patch 11: This patch introduces support for eDMA v3. In addition, this patch has been designed with an eye towards future upgradability, specifically for transitioning to eDMA v5. The latter involves a significant upgrade where the TCD address would need to support 64 bits. Patch 12: This patch focuses on the device tree bindings and their modifications to properly handle and integrate the changes brought about by eDMA v3 Frank Li (12): 1 dmaengine: fsl-edma: clean up EXPORT_SYMBOL_GPL in fsl-edma-common.c 2 dmaengine: fsl-edma: clean up fsl_edma_irq_exit() 3 dmaengine: fsl-edma: transition from bool fields to bitmask flags in drvdata 4 dmaengine: fsl-edma: remove v3 from enum edma_version 5 dmaengine: fsl-edma: move common IRQ handler to common.c 6 dmaengine: fsl-edma: simply ATTR_DSIZE and ATTR_SSIZE by using ffs() 7 dmaengine: fsl-edma: refactor using devm_clk_get_enabled 8 dmaengine: fsl-edma: move clearing of register interrupt into setup_irq function 9 dmaengine: fsl-edma: refactor chan_name setup and safety 10 dmaengine: fsl-edma: move tcd into struct fsl_dma_chan 11 dmaengine: fsl-edma: integrate v3 support 12 dt-bindings: fsl-dma: fsl-edma: add edma3 compatible string .../devicetree/bindings/dma/fsl,edma.yaml | 19 ++ drivers/dma/Makefile | 6 +- drivers/dma/fsl-edma-common.c | 267 +++++++++++---- drivers/dma/fsl-edma-common.h | 119 ++++++- drivers/dma/{fsl-edma.c => fsl-edma-main.c} | 323 ++++++++++++++---- drivers/dma/{mcf-edma.c => mcf-edma-main.c} | 34 +- 6 files changed, 578 insertions(+), 190 deletions(-) rename drivers/dma/{fsl-edma.c => fsl-edma-main.c} (62%) rename drivers/dma/{mcf-edma.c => mcf-edma-main.c} (91%)
