Patch 1 adds the FSL_EDMA_DRV_MCF flag to fix byte-lane addressing for MCF54418. Patch 2 adds per-channel IRQ naming for easier debugging. Patches 3-5 fix the interrupt and error handlers for all 64 DMA channels: - Patch 3 fixes the interrupt handler to process all 64 channels - Patch 4 moves the error handler out of the header file for clarity - Patch 5 fixes the error handler for all 64 channels with proper types Tested on a custom MCF54418-based platform with slave DMA transfers. Signed-off-by: Jean-Michel Hautbois --- Changes in v2: - Check devm_kasprintf() return value - Keep request_irq on one line in naming patch - Remove non needed memory barrier - Remove the interleave patch for now - Link to v1: https://lore.kernel.org/r/20251124-dma-coldfire-v1-0-dc8f93185464@yoseli.org --- Jean-Michel Hautbois (5): dma: fsl-edma: Add FSL_EDMA_DRV_MCF flag for ColdFire eDMA dma: mcf-edma: Add per-channel IRQ naming for debugging dma: mcf-edma: Fix interrupt handler for 64 DMA channels dma: fsl-edma: Move error handler out of header file dma: mcf-edma: Fix error handler for all 64 DMA channels drivers/dma/fsl-edma-common.c | 5 +++ drivers/dma/fsl-edma-common.h | 11 +++---- drivers/dma/mcf-edma-main.c | 72 +++++++++++++++++++++++++------------------ 3 files changed, 52 insertions(+), 36 deletions(-) --- base-commit: ac3fd01e4c1efce8f2c054cdeb2ddd2fc0fb150d change-id: 20251123-dma-coldfire-5f36aee143b3 Best regards, -- Jean-Michel Hautbois
