This patch allow EDMA driver can probe at EP side. 1. Clean up patch dmaengine: dw-edma: Detach the private data and chip info structures dmaengine: dw-edma: remove unused field irq in struct dw_edma_chip dmaengine: dw-edma: change rg_region to reg_base in struct dmaengine: dw-edma: rename wr(rd)_ch_cnt to ll_wr(rd)_cnt in struct 2. Enhance EDMA driver to allow prode eDMA at EP side dmaengine: dw-edma: add flags at struct dw_edma_chip 3. Bugs fix at EDMA driver when probe eDMA at EP side dmaengine: dw-edma: Fix programming the source & dest addresses for ep dmaengine: dw-edma: Don't rely on the deprecated "direction" member 4. change pci-epf-test to use EDMA driver to transfer data. PCI: endpoint: functions/pci-epf-test: Support PCI controller DMA 5. Using imx8dxl to do test, but some EP functions still have not upstream yet. So below patch show how probe eDMA driver at EP controller driver. https://lore.kernel.org/linux-pci/20220309120149.GB134091@thinkpad/T/#m979eb506c73ab3cfca2e7a43635ecdaec18d8097 Frank Li (6): dmaengine: dw-edma: Detach the private data and chip info structures dmaengine: dw-edma: remove unused field irq in struct dw_edma_chip dmaengine: dw-edma: change rg_region to reg_base in struct dw_edma_chip dmaengine: dw-edma: rename wr(rd)_ch_cnt to ll_wr(rd)_cnt in struct dw_edma_chip dmaengine: dw-edma: add flags at struct dw_edma_chip PCI: endpoint: functions/pci-epf-test: Support PCI controller DMA Manivannan Sadhasivam (2): dmaengine: dw-edma: Fix programming the source & dest addresses for ep dmaengine: dw-edma: Don't rely on the deprecated "direction" member drivers/dma/dw-edma/dw-edma-core.c | 130 +++++++++++------- drivers/dma/dw-edma/dw-edma-core.h | 32 +---- drivers/dma/dw-edma/dw-edma-pcie.c | 83 +++++------ drivers/dma/dw-edma/dw-edma-v0-core.c | 44 +++--- drivers/dma/dw-edma/dw-edma-v0-debugfs.c | 10 +- drivers/pci/endpoint/functions/pci-epf-test.c | 108 +++++++++++++-- include/linux/dma/edma.h | 56 +++++++- 7 files changed, 297 insertions(+), 166 deletions(-)
