This patch series fix the support of dw-edma HDMA NATIVE IP. I can only test it in remote HDMA IP setup with single dma transfer, but with these fixes it works properly. Few fixes has also been added for eDMA version. Similarly to HDMA I have tested only eDMA in remote setup. Changes in v2: - Update comments and fix typos. - Removed patches that tackle hypothetical bug and then were not pertinent. - Add the similar HDMA race condition in remote setup fix to eDMA IP driver. Changes in v3: - Fix comment style. - Split a patch in two to differ bug fix and simple harmless typo. Changes in v4: - Update patch git commit message. - Link to v3: https://lore.kernel.org/r/20231011-b4-feature_hdma_mainline-v3-0-24ee0c979c6f@xxxxxxxxxxx Changes in v5: - No change - Rebase to mainline 6.7-rc1 - Link to v4: https://lore.kernel.org/r/20231011-b4-feature_hdma_mainline-v4-0-43d417b93138@xxxxxxxxxxx Signed-off-by: Kory Maincent <kory.maincent@xxxxxxxxxxx> --- Kory Maincent (6): dmaengine: dw-edma: Fix the ch_count hdma callback dmaengine: dw-edma: Fix wrong interrupt bit set dmaengine: dw-edma: Typo fix dmaengine: dw-edma: Add HDMA remote interrupt configuration dmaengine: dw-edma: HDMA: Add sync read before starting the DMA transfer in remote setup dmaengine: dw-edma: eDMA: Add sync read before starting the DMA transfer in remote setup drivers/dma/dw-edma/dw-edma-v0-core.c | 17 +++++++++++++++ drivers/dma/dw-edma/dw-hdma-v0-core.c | 39 +++++++++++++++++++++++------------ drivers/dma/dw-edma/dw-hdma-v0-regs.h | 2 +- 3 files changed, 44 insertions(+), 14 deletions(-) --- base-commit: b85ea95d086471afb4ad062012a4d73cd328fa86 change-id: 20231011-b4-feature_hdma_mainline-b6c57f8e3b5d Best regards, -- Köry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
